Convienently, this ban omits Saudi Arabia, and Egypt. Both countries that were home to perpetrators of terrorist attacks in our country but ones which Trump has business dealings with. 
Fact is it's all smoke and mirrors meant to placate the sheeple that voted for the Cheetofuhrer. Reality is that the existing vetting process is very intense, after waiting a sufficient length of time the administration will resume entry after falsely claiming they have improved the vetting process in an effort to convince us we are now safe. The reality is safety is an illusion in today's world and Trump's military adventurism will create more future terrorists and make future attacks more likely.
