One leads to the other, let's not pretend otherwise.
No fight over Taiwan will stay non-nuclear, and once that happens, is very easy for MAD to come into play.
It does not matter if a move is 'political suicide', when the people involved already stole an election and control most levers of power.
Though I could see Biden/Pelosi ordering a draft targeted at just red areas, to help kill of the future of the Right.
In all likelihood, no conflict over Taiwan will occur, because China already owns DC, and can play a long game of subverting local Taiwanese politics.
The military training/operation angle to the whole Taiwan issue also helps prop up Xi at home, while he's dealing with mounting domestic issues. It also lets China flex it muscles and look tough internationally by flying around and violating Taiwanese airspace.
But people on both sides of the Pacific know that an actual shooting war over Taiwan could very easily escalate to WW3, and claiming otherwise is either foolish, deceptive, or ignorant.
