First Saudi Arabia got a taste of terrorism the other day, and started to shut down the terrorist groups
Recently Pakistan has started shutting down the offices of many terrorist organizations.

This is how the war on terrorism will be won. You can't stop terrorism with war or force... you have to change the hearts and minds of the public and leadership. Terrorists can only exist in a population that accepts them and grants them the resources to operate (Freedom to meet, offices, money, transportation, weapons, etc...) Without these resources terrorist organizations cannot function, simply because they do not create resources, they only use them.
For decades the Arab countries have turned a blind eye to (and in many cases supported) the terrorist activities. Now that the terrorists have started to bite the hands that fed them, they are going to go down.
That is the irony of the dictator-like governments in the Arab world... the leaders will not tolerate decent... now that the terrorists have started to attack them, they will turn on the terrorists.
