"These sums pale into insignificance when set against a total US defense budget of $715bn for 2022. The assistance represents
5.6% of total US defense spending. But Russia is a primary adversary of the US, a top tier rival not too far behind China, its number one strategic challenger. In cold, geopolitical terms, this war provides a prime opportunity for the US to erode and degrade Russia's conventional defense capability, with no boots on the ground and little risk to US lives."
