You should read the entire article. It shows that this is NOT a major pathway for terrorists as I said.
So as long as it is only a minor pathway for terrorists, you are personally OK with that?
It's kind of like trying to count noses to arrive at the number of illegal aliens that have invaded our country. The low number is about 12M while the the high number seems to be around 36M. Guess we need a low/high number on the terrorists.
Even the ones on your minor pathway...
