If you can't "eradicate" terror, does that mean you shouldn't try to limit it as best as you can?
If the thought process is that terrorists are angry at us, largely because we're involved so heavily in the Middle East, promoting ideas that go against their values. And if we use a more hands-off approach, terror in our country will actually decrease. I get it point of view, and to an extent, believe that.
Hypothetical: If we use a "hands off" approach in Iraq, and let Iraq defend itself, and Iraq is overthrown by ISIS. Are Americans safer because we didn't interfere, or less safe because ISIS is in power of an entire country in the Middle East?
