Ummm....Why is the U.S. spending more money on Ukraine than on single mothers at home?

I'm just curious about this. Why are untold billions being spent on arms for Ukraine and "economic assistance" for this breakaway province of Russia, when we have problems of poverty right back here in the good old US of A? Is it more important to blow up Russian tanks and ships than to support the American people themselves? Seems that way, doesn't it? Russia's making steady progress anyway. They're well on their way to controlling all of Donbas, and all of the Black Sea coast of Ukraine. Let's face it, as Machievelli tells us, mercenary troops like the Americans in Ukraine really aren't quite up to patriotic nationalists like the Russians there, who are actually ready and willing to die for their country. Other than causing inflation and killing people for fun, what on earth does the U.S. government think that it's doing?
