The US should leave NATO. The conflict with Ukraine and Russia was sparked in part by NATO expansion eastward over the last couple decades and US intervention in Ukrainian politics.

The conflict with Ukraine and Russia began when Ukraine rejected the leaders Russia and Putin wanted to be in power there. By wanting to be free and making their own decisions about what happens in their own country is the true reason why things went the way they did. It is the oldest trick in the book of Russia. They have done so many times through the history. Placing favorable inserts in power to then pluck all the benefits under different flag. Great example for it is Belarus today.

If Baltics weren't in NATO, they would have tried this here as well. I live in Latvia and we are one of those former Soviet Union satellites. Time and time again we are being threatened by Russia how we are next after the Ukraine.

Who else would stand up for these much smaller countries? Or the idea is that it is okay to just squash the little guys? It is okay to just squash everyone who want to have their freedom in their own land? I guess, maybe so. Maybe we should just let them. But then you will not have Europe to visit some day. It will all just be Russia here. It will be Soviet Union 2.0. I thought we all were over that shit.

On a simple practicality basis, the US cannot afford to be taxed and indebted further by foreign wars.

True, but yet somehow through the history US has found itself on every continent wherever there is something to gain anyway.
