Even if US is going for the hunt of terrorists in Pakistan, it is of no use. Iraq is a perfect example. Until the public stop supporting the terrorists/extremist organizations, it is not possible by any force in this world to stop Jihad. Pakistan nearly has 13000 madarasas preaching hatred for the students right from their childhood. Anti US/Europe thoughts are deep routed in Pakistan society. If US goes for another war with Pakistan, then it would be an end to US, not to the extremists in Pakistan. Pakistan is the epicenter of terrorism in the world - every one knows that. Every madarassa is used for terrorism, hatred & Jihad. It is 100 times more vulnerable than IRAQ.
