I'm a US army infantry, I don't have a great overall picture of geopolitics, but I'm generally a pretty anti-war kind of guy. My personal take is that while we've mixed ourselves up in a lot of deplorable wars, we also get utilized a LOT to prevent large threats from brewing in the first place. I just spent the last year on a NATO peacekeeping mission, and my job was 100% "be visible so Russian backed actors can't operate openly"
So no, we haven't fought wars that directly expelled hostile armies from our territory. But we do project a strong presence in dark corners that further the goals of stability for the US and Western Europe. By the way, NATO is mostly the US armed forces, other countries supply token, under equipped forces. That's changing recently due to Russia's aggression, but most of Western Europe was completely dependent on US NATO forces to maintain peace.
Thunder is the only one I've used so far. No complaints at all, I just wish I could, instead of building a large list of subbed communities, just filter out certain communites from my feed. Maybe it's coming, maybe we already can ๐คทโโ๏ธ
