Osama will be caught in Pakistan if US takes action and the so called war on terror will end and the other innocent people of the muslim world can breathe free .
After Osama is nabbed the wind will be taken out of the American sails and neocons will lose support for their Islamophobic agenda . And that is the reason why they dont go in to Pakistan. They will surely find Osama there and they will have no cause to use to invade other countries
