The problem with that plan is i) coordination is hard, so the threat to the US is not very credible ii) actually doing those things harms us too, either through retaliation or just intrinsically.
(eg we sell US bonds en masse, we get hit by the resulting global recession. We switch off Five Eyes intelligence sharing, we face more terror threats. Not to mention how reliant our military, NHS etc all are on US supply chains).
Long term the answer is to become much richer and militarily stronger, ideally with a large, young, highly capable population. Then all sorts of things start to shift in your favour. But for that we need to unleash growth and we are pretty bad at that. The EU, for example, unironically talks about being a ‘regulatory superpower’. That’s not really a thing, up against military and economic superpowers.
Edited to add: we can also do long-term things to make us less reliant on others for our critical national infrastructure (e.g. the EU built its own version of GPS for that reason). It all has costs though. Unless we’re prepared to accept significantly increased taxes or significantly lower public spending in other areas, we can’t do it (other than by growth, see above). Borrowing more is not viable if you are trying to reduce reliance on outside forces, becuase you just make yourself more vulnerable.
