Ukraine is not an ally. Europe can handle this one on their own.
The last numbers I saw said Europe combined is contributing nearly as much as the U.S. has.
But until Trump, Americans never insisted Europeans invest in their militaries and one result is, they don't have so much to contribute.
Some analysts / armchair generals (i.e., McGregor) tell us that Russia is not only winning but also preparing for a massive new invasion when the ground freezes in Ukraine.
They say there's no point in Ukrainian resistance and even less point in US sending aid to prolong the war.
Time will tell if they are right.
The stakes for us are the costs of victorious naked aggression -- Russia's invasion of a smaller neighbor will encourage every other brutal dictator, today and future, beginning most likely in Taiwan, and from there, anyone's guess.
Ukraine is our 1938 & Munich, "peace in our time".
We will not like that world and Ukraine is our opportunity to prevent it.
