I doubt there’s an easy solution. Right now the play is squeezing Russia at a slow pace, hopefully causing the country to bleed itself dry and most of its people there calling for a war to fizzle out and running them out of a fighting force. Continue keeping Russia in a state of hardship.
Taiwans rule. Foreign tsmc fabs have to be a gen behind. This would definitely change if China took over Taiwan, but who knows what China will do or allow at that point. They could shut the whole US fab down if they want. Even if they did try to re-tool the US fab (taiwan or china or tsmc) in a few years, it would cost billions and a lot of time to get it done.
