Sorry to break it to you, but you can’t.

There are a few remaining checks and balances on other issues, and the Democratic Party might be able to use its minority in Congress to strategically delay certain things. But foreign policy is entirely in the President and Congress’s domain. And while Republicans in Congress sometimes have internal bickering that derails their agenda, I expect Trump and Congress to march lock-step on this one. (Their marching might even be a bit like a goose step, come to think of it.)
