And they are after the deals are signed, no?

A lot of deals got ripped up on "Liberation Day", including some Trump was extremely proud of when he announced them in his last term. He's changed his mind several times in six months already, dropping deadlines and tariffs when the market gets itchy feet, imposing higher tariffs due to disputes with governments completely unrelated to trade. He loves to make grand gestures to distract from domestic issues, and his administration showed so little basic competency they actually publicly announced tariffs on uninhabited territories full of penguins. Why would anybody assume stability?

To echo a comment made in a parallel thread, decisions made to invest in US manufacturing don't get made by people dumb enough to take Trump at his word.

And even if he wasn't tariffs are unlikely to persist at those levels under the next President, regardless of who that is, and that's the sort of timeline you pay back your investment in US manufacturing over...
