I saw a TikTok video yesterday from a reliable source for military-themed content that Iran was importing & hording fuel for their estimated 800 ballistic missiles capable of reaching targets throughout the Middle East & into lower Europe.
Based upon that, I'd say a military conflict with Iran will occur; the "when" is the only unknown variable.
And FWIW, Trump's call to Putin allegedly dedicated a lot of time to this topic, with Russia allegedly agreeing to not intervene or support Iran, especially since so many Middle Eastern countries who are on good terms with Russia have been identified as Iranian targets. Also, Russia's relationship with China is apparently showing signs of strain & conflict (which is historical & nothing new frankly); therefore, Iran's only 'guaranteed' allies at this point is Yemen, MAYBE Turkey to some extent, South Africa, some other unimportant African nations, & China (via proxy).
