I disagree. We cannot police the world, and I don't want to pay for it.
A better use of our money and the time of American soldiers and other agents is to watch suspicious activity and people HERE.
I don't really care if some American somali goes to Africa and trains to be a terrorist. Have at it. I care when they are allowed back onto American soil.
If we put all of our effort into watching the borders and immigration, we wouldn't have to try to pay attention to what every person is or isn't doing in every country around the world.
That said, if the U.S. is worried about terrorist training camps then bomb the crap out of them every time one is identified.
But chasing the terrorists down if they are there is good too. They only understand brute force. Take no prisoners. But this dude is not the one for that because he ties their hands.
