There are many good points in this response Dylan. This is one of the reason I dialog with you from time to time. America (our government) betrayed Ukraine is likely not in doubt.
The fact that profit has crept in is something that should have been expected since this is the method of operation of America in most if not all of its dealings. Biden is one of the worst in this department.
I cannot draw a parallel to German aggression in the 1930s. There was also Russian communist aggression during this period. War was bound to happen based off the end result of WWI. Hitler went through the Allies in his first attack in a matter of weeks. The fact that the allies were able to outlast the Nazi had as much to do with luck and Hitler's blunders as anything.
As far as the right thing to do. This is always subjective. I have seen the suffering of Americans economically caused by the powers that be. I cannot support any more foreign entanglements of this sort until our leaders start dealing with these issues.
What I do not like is the Ukraine flag waiving and demand that if you do not support them you are supporting evil. This is bogus as fuck.
One of the main reasons Ukraine enjoys so much support is they are white. If this were Uganda instead of Ukraine, the majority of Americans and our government would not care.
