Of course, it's very easy to capture these people. You just go out there with a butterfly net, right? And how much of an expert on counterintelligence in this specific area are you? What intelligence should we be risking American lives to gather?
Have you ever heard of a place called Guantanamo Bay Naval Base ? U.S. Marines called it GITMO.
After 9-11-01 during the Bush administration the U.S. needed a place to incarcerate captured terrorist off of U.S. soil so liberals and the ACLU wouldn't be intervening in behalf of Al Qaeda demanding that terrorist be protected by the Constitution. GITMO seemed to be the place.
558 suspected terrorist, Al Qaeda leaders and unlawful combatants including the mastermind of 9-11-01 were captured and sent to GITMO.
How many were captured during the Obama administration ? 0
How easy is it to capture "these people"? I suppose it depends how competent an Executive administration is.
