History has also proven that most wars are pointless and solve nothing, it's easy to send other men to their deaths if when politicians aren't the ones fighting them. Have we not learned anything from Afghanistan? We cannot get involved in sectarian violence and have any form of success in the long term. Ukraine is a complex nation full of plenty of pro Russian factions and anti Russian factions, they are more than capable of defending themselves. This isn't Russia invading Ethiopia against an enemy that can't defend itself. We cannot afford as a nation to get bogged down in an endless war wasting trillions of dollars with no end game. We are going to solve the friction between Russia and Ukraine. It has existed for centuries. It won't end no matter the outcome of the present escalation. Russia isn't going to steamroll Eastern Europe, that is pure lunacy created by the war hawks to distract from the issues at home. This is a Europe problem that needs to solved with European solutions, not a US problem. WW1 was a century ago and WW2 was 70 years ago, the French and Italians, along with the Germans need to step and drop the excuses of the destruction they suffered during those wars as a reason for the US's needed role militarily. They can sit idly on the side and watch much of Ukraine fall to the Russians or they can get involved outside of a few speeches and summits. Maybe they will be forced into actually doing something or not, either way it should be clear that we cannot fight every issue that pops up in Eastern Europe for them.
