The way to protect ourselves is to stay out of those Islamic crazy countries.
It is prudent not to go into those places and not to let anymore of those people to come into our environment, regardless of what the government says. The government does not have our best interests forefront in their minds, they have their interests in their minds.Their interests are more people, more money. If we are nice, they may be nice back, or not. The government people live in a protected environment, while the citizens do not.
But what do I know?
