Pakistan state sponsor of terrorism

Dear Mr. President,
My name is Ashish Pawar, I am from India and its a warm request to you to take action against Pakistan. I remember the attack made by Osama-bin laden to World Trade Center of US, but I think it was not actually the Osama attack, it was Pakistan who stood behind him for the cause, but the revenge was taken by US government by killing Osama is not the justice for the innocent people who died in world trade center. The latest attack by Pakistani backed terrorists on Indian army base in Uri which took lives of 17 Indian soldiers has outraged Indians and other communities around the world. It is time to accept the reality that Pakistan has been providing a safe haven for terrorists, therefore to designate it for what it is: a state-sponsor of terrorism
