Protectionism is the use of scare tactics, the use of unsound scientific information in an attempt to protect our market. In this case I believe that sound science dictates that it is time to open the border.
I don't think anyone who has followed the progress of the Islamofascist terrorists who have threatened us believe we are going to be safe if we try a fortress mentality, to step back and say no one is going to hit us, they don't care about the United States. They do.
