We fought the first (and second) Gulf wars because we needed middle east oil. Due to fracking we are essentially energy self sufficient. So the middle east can (literally) go pound sand.I think you underestimate the long term consequences of Ukraine or Taiwan being conquered.
You are correct about conquest being older than history, and that it is almost inevitable.
What you're wrong about is thinking that this is just about who gets to run a couple of minor countries.
In the past conquest had regional reach only. Most of the world wouldn't have even known about it.
But for the last 2 centuries or so it has had a global reach. In today's hyper connected world either would have an immediate and disasterous effect, followed by a much larger issue.
These things have a habit of turning into world wars.
Do you think we fought the 1st gulf war because we give a shit who's in charge of that tiny piece of sand ?
Neither Ukraine nor Taiwan provide critical resources. The democrats think Ukraine is critical because that is how they launder billions of dollars (aid money goes to Ukraine; Ukraine hires American consulting firms who happen to employ children and relatives of democrat party leaders; aid dollars are returned to this country). But apart from the opportunity for graft neither nation is critical to the US.
But people say conquest of the Ukraine or Taiwan would only embolden the dictatorships of Russia and china. That is true but the gains would be short lived. The truth is that both Russia and china are dying states. They are both in a demographic death spiral that is impossible to reverse. They will die of their own accord. Because of their underlying instability we should seek to avoid getting entangled with anything that could lead to war.
If we are smart and play the long game we should let them implode and not give them an external threat to rally their people. Let them waste their very finite resources without sacrificing American lives.
If we were to go to war with china it should be based on their cooperation with the Mexican cartels to flood this country with fentanyl that results in 100,000 lives lost per year. Not because they want to reclaim some lost real estate. I'm not joking. We should expel all Chinese college students and prevent any Chinese ship from docking at any US port as a first step. If that doesn't work then start sinking Chinese ships on the open water. Hit these cocksuckers where it hurts until they scream for peace.
Cold as it sounds we should not go to war over Ukraine or Taiwan.
