When it comes to Ukraine, I really don't trust what anyone says about any of it.
A healthy attitude.
There's too much propaganda involved from all sides.
Another healthy attitude for you to have. Remember, there is no side that feels as though it can ever issue too much propaganda.
I'm mostly coming from a general position of being sick and tired of all the endless foreign wars
Another healthy attitude ... up until the option is to have a civil war instead.
Remember, wars are going to happen in the world. They are beyond our control. The question "we" (the Marxist "we") need to ask ourselves is how will any given war(s) and the propagating politics affect us here at home? You have to admit, it's one thing to claim to support Ukraine in its fight to repel Russian invaders, and another thing entirely to consider a Russian hegemony in Europe, especially when you see how Russia plays hardball with other countries the moment Russia perceives it has some sort of advantage.
All this is to say that a war is just the visible symptoms of deeper international politics going on. When you inevitably see the next of the endless foreign wars, ignore the war at first. Learn about the political situation under the hood first. Then determine your position on the war, to include what the US should do, and how it should support if that is the correct thing.
Regarding the overhyped nothing-burger in Ukraine, I would direct your attention to the US' support for the Ukraine army, which is a limited supply of high-tech rockets. These particular rockets are a sort of "trump card" that allow Ukraine to selectively take out key targets ... but they only have a limited supply so they have to use them wisely. One rocket is sort of a guaranteed elimination of whatever they select, so if they waste one on a jeep, they won't have it to take out the heavy bomber when it is sent in. This alone is preventing Russia from steamrolling in with any expensive/irreplaceable systems that they can't afford to lose because they know that Ukraine will be more than happy to take them out. As Russia stalls for time in totally defensive positions, Ukraine keeps picking them off one by one. There is only one ending for the situation in Ukraine and Russia will not be on the happy-ending side ... so there is no reason you need to be worrying about it at all.
and all the money that goes into them, rather than addressing the plethora of domestic issues (border/trafficking/invasion of illegals, poor infrastructure conditions (e.g. road/rail), etc etc... "clean up your own room first before trying to clean up the rest of the world".
You are absolutely in the right. Afghanistan was my big complaint. The amount of money spent there just to "give it away" still bothers me. That was a
lot of money. But the Ukraine isn't really a cause for concern. The amount of money we are spending there is negligible. As least I have some good news for you on that front.
