It's a tactic, agree to the deal, the US ignores us. Allow the deal to get destroyed in parliament and the courts and it has no effect. The deal was a means by which to get enough time to figure out the correct response. We've been doing this kind of thing for decades.

This is the way. The current US administration is a 2 year old with ADHD and shiny distractions abound. Agree to deals and let him claim wins, and then bury it in bureaucracy and common sense.

This is, essentially, how the US government survived Trump 1.0, and is why Trump 2.0 has been so concerned with gutting bureaucracy and placing vapid yes-men in the cabinet, but they can't really do that in Europe.

It's one of the few times where EU bureaucracy is a huge advantage.
