Terrorism fails
The Romans did a pretty good job of controlling terrorism with military force.
In our modern enlightened western civilization we are rightfully reluctant to use Roman innilation tactics.
Recent revelations of muslim plans to assassinate the pope are clues that our problems with Islamic terrorism goes way beyond our support for the Jews. Islamics are going to keep killing us and we will keep killing them until we figure out how to stop them, short of removing them from the planet.
