Well, let's see.. two possibilities here:
1. He does not do much as you suggest -- then he is toast. Might even get impeached. Democrats win the 2018 elections, and probably 2020 too.
2. He does respond. Balance in the US shifts toward the republicans, since more democrats live in the coastal areas, to be hit the hardest. GOP wins the 2018 elections... if such can be organized, of course, and this is doubtful.
Best not to get to this decision fork at all.
A flaw in your logic there. Don’t forget all the missile launch sites in the midwest, Air Force bases such as Offutt, Malmstrom, Barksdale, and others.
That happens to be where a whole bunch of Trump-supporting Republicans live.
