Chairman Pakistan Tehreek-e-Insaf (PTI) Imran Khan has said that US-led war on terror has cost Pakistan more than any ally and it cannot afford further participation in it. Talking to a foreign TV channel, Imran Khan said that use of force was not resolution of all issues. The war on terror cannot be won by bullets only, he said. The PTI chairman said that Pakistan was not position to continue support in war on terror anymore as the collateral damage caused by this war has increased extremism in the country. Imran said he wanted the army to work within its constitutional limits and refrain from the policy of controlling the politicians. He said that Pakistanis, like the people in Middle East, have risen against the 'family mafia and status quo. The PTI chairman said that he has declared his assets and offered to quit politics if his declaration of assets was proved wrong.
