My post was accurate, your isn’t except for the part that agreed with mine, you just don’t see how much we support Ukraine apart from the weapon sales, and no one is paying us for the training we give the Ukrainian armed forces, or for all of our connected military exercises and troop movements in the region, and for our basic military posturing and buildup that is focused on Russia.
And the extra sales mean at least a partial subsidy for increasing the size of the US military industrial base.
We also gain training in a far more realistic environment and valuable feedback about the performance of our weapons in actual use.
The Europeans could seek to make a deal with China to protect them from Russia. Allowing all of Eurasia to fall into one, huge, anti-American power would be the height of folly. But for that reason, I wouldn't put past the ability of our stupid political class.
