Something I find fascinating is the sheer political ineptitude of rolling up terrorism, immigration and refugees in to one big messy ball and acting against all three simultaneously, without a clear message about what the point was of all this disruption. Bringing people with valid visas into the action looks like a totally unnecessary own-goal. Do you think Google, Apple, Facebook and Microsoft would have teamed up together against a well-crafted, well-articulated action against possible terrorists coming into the country? Perhaps using an NSEERS-like system of profiling?
Nope, Trump, Bannon and Miller seem to think offending the maximum number of people possible would be helpful and the scale of the blow-back seems to show that was a miscalculation. (On the other hand, every other apparent miscalculation they made in the election campaign played out ok, so perhaps they really are the political Forrest Gumps they appear to be.)
