Trump, and now his administration, have been targeted for well over a year for many of the positions well known to Americans.  In spite of this, Americans and their voting system supported him.

 The age of giving a free pass to those who claim to be refugees has come to an abrupt end.  This is based on events of 2015 and 2016, and before, that have taken place internationally and domestically.  It targets countries at war with terrorism that need assistance defeating it.  It begins by implementing security at their borders.  It is inconvenient.  It can be unfair and unreasonable but it is an implement now and correct later policy.  It is also a policy that will unlikely be overturned no matter which Party is in power in the future- the beneficiaries of the government that had to do the dirty work.
