Beyond the N.E., martial law and military tribunals you brought up a good point, the Constitutionality of some provisions, ripe for law suits, just like the left likes to do! Now it wouldn't be Trump's people directly (or I guess it could be, a new DOJ Head who doesn't "agree" with The President or knows a veto would be over written) but I'm sure many folks would be happy to bring suit and tie up said provisions in courts for a while! Just thinking out loud.
