Our political leadership is clearly a disaster. The US isn't quite on the brink of civil war but it's not impossible to conceive of. The Democrats keep insinuating that half the country are domestic terrorists, and conservatives are feeling like their nation has been hijacked by neo-Marxists who really mean to rip up the Constitution. Both sides hate each other more than they hate the Russians and the Chinese.
Military leadership is incompetent as hell. Afghanistan, obviously. But with the exception of Gulf 1, I can't think of a war during my lifetime where a bunch of goat herders didn't hand us our ass. We had overwhelmingly superior technology every time and we still lost.
Our intelligence sucks. We never know what's going on and we're constantly taken by surprise. Do you think just maybe Russia and China have gotten together, and allied with Iran plus umpteen other nations? Do we really think Putin has put no thought or planning into this?
Besides, doesn't like half the Ukraine want to be part of Russia? Whatever. How is this our problem? The US can't beat peasants with AKs when we're pretty united, and it's barely keeping its shit together at home as it is.
This is not a good idea right now. People are not going to rally together. It's not a conflict we can lose and everything remains basically ok, like Afghanistan or Iraq or Vietnam. It is certain to escalate. We lose to Russia and China and it could be the end of the USA as a nation. Our enemies have their shit together. We don't. Not at all. I don't think we'd win. Or maybe I'm wrong and somehow we do. Either way, maybe someone isn't willing to lose. That button is always there. This could really open the gates of hell.
