Until a majority of our Politicians accept the fact that we are involved in WW3, these things will continue to happen.
The terrorist KNOW they asre in WW3. They started it. They want it. They can not destroy civilization unless they war against all civilization.
We are not involed with people in criminal acts, a Police Action, a Peacekeeping mission or another nonsense PC term for WAR. We are in WAR
A lot of them do know we're in WW3, but they're rooting for the other side.
