If we get as much for the next $40 billion, I'm pretty sure we won't have to go to war with Russia for a very long time.
There was no reason to think that Russia was going to attack Ukraine. They promised they had no intention of invading.
Actually, they seized part of Ukriane, bloodlessly, in 2014. Then they have been engaged in hostile activities in Ukraine in the Donbass region for several years. So, an invasion wasn't shocking.
In the larger sense, though, why does it help American interests to have a proxy war against Russia? In the last two wars in Europe, they were actually our ally. And we currently have no specific reason to be at war with them in any case. They have become a favorite villain of the left, but that's more propaganda than actuality.
Why is Russia our enemy? And why are we spending billions of dollars, (that we don't have, and will be added to our debt) to fight Ukraine's enemy? Why are Ukraine interests our interests, all of a sudden?
