To be clear, I didn’t necessarily state I advocated for those things, but the prompt was for what interests the US has in being involved in Ukraine.
Whether it is right or justified is another matter, but it is undeniably of significant importance for a state to be able to show it can project force/inflict harm on those it deems a problem.
As for US involvement in the Middle East…yeah…not great. US involvement in Ukraine? I’d say it’s a different story since we are actually wanted there by the Ukrainian people, and it is reasonably likely that Russia would be involved in Ukraine whether or not it wished to be involved with the West, as it is valuable land in an area of historical Russian influence, and the crackpot ideology of Putin’s Russia all but demands its subjugation (no, really, shit’s wild).
