First, you not wanting to send money and weapons to Ukraine to fight against Russia and saying Ukraine is the most corrupt country in Europe, already shows that you're some Russian incel lol. That's only a Russian talking point. Ukraine is fighting for their country, Russia is fighting to take it and losing horribly because Russia is led by pathetic, weak leaders. I would happily send more and more weapons to Ukraine until Russia is at its knees without Moldova nor Crimea.

Also, you've given a completely non-expansive view of what the Afghanistan war was about. You fail to include the view that, if we left all things alone, Russia would control most of the world's oil. To you that's just an acceptable outcome and we shouldn't stop it. Russia was already doing proxy wars in these countries, so the USA stepped in to stop Russia. "War is bad" isn't an answer. War is bad but happens for a reason.

Funniest among your claims, the US did invade Iraq with UN permission. So it was a legal war. It was later decided there hadn't been enough evidence, but later is too late. The justification for the war: we went on the assumption that they had WMD which Saddam loved to brag about. We went because he was casually using chemical weapons on villagers, genociding the Kurds. And we went because he was breaking peace treaties casually. The reason for going to the war is more likely to make allies in the middle east, to supplant the current governments with Democracies, but the justification were as previously said. Russia, on the other hand, did start an illegal war.

Also, if China attacks Taiwan we'd 100% support them and probably send ground troops. They manufacture a huge chunk of our microchips and the other huge chunk is made in ... China. So you know, 'war is bad' doesn't really suffice again. Also which country are you from? I hope you're not an American with this simple view? I am 90% sure you're Russian with that Ukraine BS.

The funniest thing, though. I don't claim to support the long war in the middle east. I do intend to understand it instead of whine like you. Apparently the illustrious US leaders thought we'd be supported with open arms by the Iraqis after quelling Saddam Hussein, but this was BS. We wanted to make a massive ally out of the middle east, and so sent troops to stabilize the region and create Democracies. It was a foolish war, and a foolish war leads to death like any other war. The American people were tricked into thinking it was a necessary war, but I doubt it really was, and in retrospect many would agree with me. Nonetheless, the reasons to go to the middle east were convincing at the time, and people wanted to create a world where Saddam didn't get his genocidal hands on nukes.
