The Terrorist’s Main Port of Entry

The main port of entry for terrorists remains unguarded. It is not the [HASH]SouthernBorderWithMexico. In fact, of all of the terrorist attacks in the U.S. none of the perpetrators have arrived from there and they all have legally entered in the country. While a few terrorists have come from foreign countries, since 9/11 the vast majority were born here. Therefore, we must accept the fact that the most dangerous and virtually unprotected port of entry for terrorism is the human mind and no wall is going to prevent ideas from entering.
