A US Army psychiatrist, Major Nida Hasan killed 13 army men and wounded 30 others at Fort Hood USA. I think this incident took place because of anger and frustration that flows from lack of peace in Palestine. The US Congress and Senate are responsible for this carnage. They have been blindly supporting Israel and not listening to the legitimate demands of Palestinians despite there being 31 UN Security Council resolutions pending against the rogue Jewish state. United States is now more than 200 years old and has may be started aging as an axis power. The whole world has turned against it. The best course for America in these circumstances would be to go by the book and treat every country according to the international law and UN resolutions. -ZAFAR ISRAR, Karachi, November 9.
