> He wants to choke them with tariffs (and now has leverage to get the rest of the world to join in).

Like, how? You expect the countries to put tariff on Chine, risk to have tariffs put on them by both China and unpredictable USA? He is loosing leverage here rather then gaining it.

> They want Greenland to defend the North

Right now, Greenland sees America as the biggest threat to protect against. They even refused to talk to Vance on his visit.

> He wants to onshore manufacturing as a strategic wartime capability

That is inconsistent with tariffs on everything. If this was the goal, he would had targeted tariffs to ease manufacturing. It would exclude materials for example. It was NOT be calculated as ratio of trade deficit.

And this is also inconsistent with using tariffs as a leverage in negotiations which was your other point. This would require stability and companies being confident the policy wont change in the next few years. In reality, they dont know what will happen tomorrow.
