Leaving aside democracy, people lives and stuff you clearly don't care about, it directly impacts Americans' safety, security and economy
First of all, you save lives if you can end a war sooner than later. Second of all it actually does not impact American security as much as you think. Why does America have anything to fear over Russian control over the breakaway regions?
destabilised Europe will drive up inflation in the US and disrupt supply chains
You are destabilizing yourselves by not pushing Ukraine to make a quick agreement. Russia will only take more territory and more lives the longer this goes on. You cannot seriously think they can beat Russia?
if Russia gain from the Ukraine war China will be emboldened to invade Taiwan take on American interests globally impacting on the US economy
It is inevitable that China will retake Taiwan imho. Why do you think the US has TSMC produce domestically? Think they will also partner with Intel.
So to conclude even if you selfishly don't care about the rules based global order
Believing in a ‘rules-based international order’ is like believing in Santa Claus at this point. Only Westerners ever actually believed in it
Ukrainian lives, or European lives, then know this- a war in Taiwan would hit Americans deeply in their pockets and your power in the world would be utterly depleted. An unkind part of me thinks it would be just desserts. But sadly you lot would bring the rest of Europe down with you
It is very odd you say you care about Ukrainian lives when you want to prolong a war that will only kill more of them, for no real gain.
