The travel ban put in place by the administration is a form of paranoia. I believe the real problem exists on US soil. Yes, the US has to uphold the position as a resourceful nation.
I don’t believe the current administration holds the interest of the people. Seems like more a person endeavor. The media helps perpetuate a lot of drama. Meaning the US law enforcement agencies needs help.
The travel ban may influence other countries to do the same. Many European countries did not require visas. This may well be a situation.
