Bored and I love thought experiments like this. Only rule is consequences must stay within timeframe of said conflict to keep from getting too abstract, i.e. Alexander conquers Afghanistan and the Twin Towers don't fall sorta thing.

The one I ponder on most is Dunkirk. Briefly put. Germans capture or kill all Brit and Canadian ground forces at Dunkirk. Germans risk a ground invasion despite lack of air superiority knowing Brit ground forces would be few and inexperienced. Germany succeeds and sues for peace with America. Resources are allocated back to Eastern Front and hold off Russians indefinitely. Third Reich becomes a reality.

Feasible?

I still don't think that the Germans could have conquered England even if they captured or wiped out the English troops at Dunkirk. The Germans never developed a way to transport troops across the English Channel.

For BQ90, even if the Japs had sunk the Pacific carriers, I don't think they could have taken Hawaii. Without that, the US production would still win, it just would have given the Japanese a larger head start in the Pacific.

Nice! Thanks for giving me something to do. Stuck at home bored to tears. I will give my thoughts on each of these for fun. Feel free to disagree or refute anything I say! Makes it all the more fun and what I love about these kinds of discussion.

A third wave would have been devastating, especially since they almost assuredly would have went after the fuel farms. machine shops, and weapons and parts store that were left mostly untouched after the first two waves and were paramount in being able to quickly mount a response fleet back into open waters. If the carriers were lost, Midway falls no doubt. Would have been the next link in the chain for Japan. US might have reached a point of no return for taking back the Pacific. Hawaii may have been invaded. The Mainland of course would have been fine, but Australia, and the Philippines may have been lost forever.

Quote:

Firm believer that if this happened the battle would have been won by the second day by the confederate forces. Tactically would have changed everything. Strategically not a damn thing IMO. Gettysburg was a strategic null in the war. Just happened to be the place where two blobs of men smashed into each other. I do not think it would have been a knockout blow to the Feds. Might have drug the war out a little longer but the end result would have been the same in my eyes.

An invasion of England would have been incredibly dicey. They did have a way to invade via converted barges. Would have been an oldfashioned invasion though which means a port would have to be captured first. A lightning strike into a small port to secure the first wave of Nazis I think might have worked. That mixed with a concentration of Luftwaffe aircraft to suppress RAF fighters and bombers and what naval units were there at the time MIGHT have led to a successful invasion. Whether sustainable or not is another story of course. The fact that a poorly led and trained Home Guard and nothing else ground wise definitely helps swing it back to the Nazi's side. Especially once airfields were captured and used by the Luftwaffe themselves. One of the scenarios I love pondering.

Hawaii I agree would not have fallen. no matter what. (barring same outcome out of Pearl as it happened historically)

America would have been in zero position to do anything in 1940, to do anything about it.

A ghastly proposition for Allied High Command for sure. I do not think it would have changed the outcome...just the timing and the body count. Even if it nullified a French invasion period afterwards the Italian front would have slogged it's way up eventually. With Russia going nuts on the Eastern Front, I think it was a sealed deal one way or another.

I always thought Lee was kind of an idiot for engaging there in the first place. Then again, I have the nice ability to know the aftermath and second guess a great general. If on a battlefield of his choosing and preparation, I believe he could have kept his North Virginians intact and at that point who knows what could have happened. I also think with his victory at Chancellorsville and the need to answer to Grant at the time led to why he decided to go all in at Gettysburg.

An interesting one that I have not put much thought into. Hmmm...From what I do know I imagine it would not have made a very large difference overall. Maybe. It would come down to timing. I believe there existed a very brief time frame where Russia, if under more pressure, may have buckled. Another front by a hardened enemy could have been just the thing to tip the scales. I think it would then come down to what kind of power Japan would have been able to project against Russia in 1941. They were absolutely bogged down in China and Korea at the same time. I am not aware of any meaningful Japanese power that could have been projected against Russia during that year. If you take the timing of Russia collapsing and the power of a Japanese force as sliding scales, I am sure that there is some point where both could line up however to have an appreciable outcome on the war.

Nice. I like this one. Gets into the real nitty gritty of these scenarios. Would we have eventually declared war ourselves? I have no real idea. I would think we would have but I can also just as easily imagine not doing so against Germany. At least not with out more direct provocation.

Adolf still has the "stab in the back" angle plus the Depression still destroys the German economy. Doubtful Weimar survives no matter what. Germany was not ripe for any form of democratic governance. If not the nazi's it would have , more likely , been the communists in power.
Now that is a good what if.
What if the reds out "thuged" the brown shirts in the early 30's ? The numbers and popular support were close . A 1930's alliance between Soviet Russia and Soviet Germany ? Europe would absolutely fall except for the U.K.

Easy:
Germany starts the war with 120 U-Boats. England is defeated before they can perfect ASDIC and Huff-Duff. It's really the only change-on-thing and the Germans can win. With enough boats, Dnitz could have dealt a crushing blow to England. I'd say if you wanted to pair two what-ifs and say adequate U-Boats AND a defeat at Dunkirk and England was done. Sure, Germany couldn't invade. But England would be starved into submission. Unless Roosevelt wanted to start straight-up American convoying of ships in 39-40 instead of mid 41, it's over.

One I have always wondered about is what if there had not been any atomic spies for Russia in the Manhattan project? It is widely acknowledged that the Russians got a huge head start from the info they got from Klaus Fuchs, Cohen, Hall, etc.

It has been estimated it may have saved the Russians up to a decade of time to develop their first nuke. Truman used our nuclear monopoly to threaten Stalin to withdraw Soviet troops from Iran in 1946 after the Russians failed to withdraw like they had agreed to.

Let's assume it really saved the Russians a decade, meaning the Russian's first nuke was late 1950s. What else would have been different? Would the Korean war have happened? Would the East German worker's revolt in 1953 been successful? Or the Hungarian revolution of 1956? Meaning we could have threatened Russian to back off or else? Would we have invaded Cuba after Castro took power in l958? Or on a larger scale, without the atomic spies, would the US even have acknowledged the communist threat in the early 1950s?

Well the Japs would have taken Midway without much effort. Also would they have been successful in Coral Sea and could have taken all of New Guninee and then maybe even Australia.

What if, Iraq never invades Kuwait on August 2, 1990?
What if George Herbert Walker Bush doesn't respond with an American led coalition?

Most Americans still won't know where Saudi Arabia is. Saddam Hussein and Osama bin Ladin are probably both still alive. Nobody knows who Wolf Blitzer is, 24 hour Cable News doesn't dominate our media news feed. The World Trade Center Towers are still standing. Americans can still board a plane without taking their shoes off at security. Nobody has ever heard of Bashar al-Assad and/or the Islamic State. Afghanistan is still a Russian problem.

George W Bush never invades Iraq, Obama and subsequently Donald Trump never become President of the USA.

I think we still have the dot.com/Y2K bubble and the subprime crisis. But, due to the follow-on actions, if Saddam never invades Kuwait, I think the world remains a much better place and I think Americans remain much more prosperous.

On Civil War ones, without trying to narrow one down, would just propose and ask --- why are some of the naval actions not looked at closer for the missing `decisive moment'? If Farragut is repelled from New Orleans, if New Orleans, Memphis and Vicksburg not only never falls, but is never really brought to siege from both sides of the river and the South is not cut in two ----- how crucial is that? I think the efforts of the Union commanders Farragut in the south and Porter in the north belong to the all time greats of American history afloat, and are somewhat overlooked by comparison.

Roman history fans have to wonder just how much may be different if Cleopatra and Antony somehow pull off victory against Octavian. Remember in ancient history especially, `victory' can just as likely take the form of something like Octavian falling to illness at the wrong time, or an inclined assassin that made one choice rather than another. The personalities matter so much, as they certainly would make a difference here.

For example, if Antony and Cleopatra do prevail, at Actium, or ashore, you don't get the 1st Century Roman Empire of Augustus. Because even though the Republic would continue to unravel, and there would be an empire in all likelihood --- the temperament of Antony and Cleopatra is unlikely to have been methodical and special blend of `real-politik' by which Octavian became Caesar Augustus and established the Principate.

Change the Augustan stamp of the 1st C BC and AD alike, and much, much else also changes, even if the Roman Empire and many of the players continue (as they surely would) on the stage much like before.

In regards to the Japanese attack the Soviet Union and it coming down to a matter of timing when would the right moment be? Coordinate attack on June 22, 1941. Imagine that one. Literally two knifes to the back of Stalin who believed in th non aggression pact with Hitler, and now Japanese troops pouring over the border at the same time.

What about at the Wehrmacht high point, around Dec. 1941, literally within eyesight of down town Moscow. Now the Soviets are rushing trooops West for operation Typhoon when BAM, several million Japanese pour across the border. Now of course Stalin would meet the most direct threat (Germany) but then several million Japanese are now inside the Soviet Union. (Of course this depends on the real evens of Dec. 1941 not unfolding in the Pacific)

Spring/Summer 1942 as the Wehrmacht again steamrolls across Russia towards Stalingrad? 1943 during Operation Citadel?

I think a properly coordinated Japanese/German assault could have brought the Red Army to its knees. It only in 1941 or 1942. After Stalingrad the Soviets were unleashing there own hell on the Germans and while it would have taken time had the manpower and mentality to wipe out any Japanese invaders

Are there Russian oil sources in range from the eastern direction? The key to averting the December 1941 choice by the Japanese Army is them having a source of fuel to offset the embargo (the major point of the campaigns in Malaya and Indonesia--to subdue the area and seize its oil sources.) The Allied response to the Japanese invasion of French Indo-China in July 1941 is the main driver of their timetable.

If there are, or have some kind of truly elaborate deal with Nazi Germany to coordinate in this way, it at least is barely conceivable on paper. But those Axis powers had very different worldviews and wishes.

What if the Luftwaffe had finished off the RAF rather than turning its bombing attention to the cities? The RAF was on the ropes, I would think it would not have taken much more to clear the skies over England of Spitfires and Hurricanes; after that a cross-channel invasion may have been more feasible, provided the Germans developed reliable means to do so.

I can definitely see your top point as being feasible. The Weimar Republic's death was a foregone conclusion anyways. Not counting reparations the entire country was devastated anyways. Leaving that power vacuum where the Nazi's slid in. Not a far stretch, at all, to imagine the Reds taking that same vacuum.

As far as your second 100% agree. Nazi Germany is what kept us from an entirely Red Europe. I am absolutely convinced of that.

Had the honor of meeting an old RAF pilot. He started in fighters and worked his way up into a position in fighter command during the Blitz due to injuries.

He mentioned to me once that there was a point during the darkest days of the attack where the RAF was within days of absolute collapse. The only thing that truly saved the RAF in the beginning was the switch from tactical to strategic strikes by the Luftwaffe. Once the pressure on the airfields eased up the Brits were able to claw back from that ledge.

I remember reading a fascinating book on the Blitz as a kid and the author made the exact same point as well. I of course cannot remember either the book or the author.

Definitely a long chain of very powerful what ifs. I am not sure I can see every single one of them but I am on board with the '91 invasion as being the most pivotal point in our ME interactions to date. That fork in the road of invade/ do not invade is huge in terms of ME stability currently.

These two are easy. Confederates win the civil war. And British defeat the Colonials(at least for the time being, not sure if that would have ended the Revolution per se...militarily it would have for sure though.)

Fair enough. So what if the German Navy manages to take control of the French Navy rather than most of those ships being scuttled or sailed to friendly/neutral ports?
