If you think Taiwan shouldn't cease to exist, how else can you guarantee that? It's either nukes or US protection and nobody trusts the Americans anymore.
Taiwan makes some of the most complex devices humans have ever constructed! They can figure out the almost 100 year old technology to make a gun bomb nuke.
I'm Australian and I already don't trust the US to help us.
I've literally never thought that the US wouldn't help us before Trump came to shit on everything.
Now I imagine we'd have to buy Trump off with "raw earth" or something in exchange for not being abandoned to China, and our head of state would quite possibly be berated publicly for wanting some kind of security guarantee for his people's future.
It's sad, I still feel like the US and UK people are closest to our values, but Trump only works for himself and his billionaire crony parasites.
He will end up with the loyalty he has earned.
Everyone around Trump hates him, and the US is heading in the same direction.
so your alternative of inaction involves a likely outcome of raping and murdering thousands of civilians in the name of peace for thousands of soldiers.
the us can do plenty of things without spending billions of dollars that are short of this, and yes, i have personally donated to the Ukrainian effort.
An obvious alternative is to increase support to Ukraine to give them what they need to expel Russia. The good old USA has the resources to do that but Republicans have blocked increasing aid at the orders of Donald Trump for years now. And now that he is in power he is finally blocking it altogether.
You want the war to end so that Poland, Japan, Taiwan and Australia no longer trust that the US will help them and develop their own nuclear weapons!
