NEW YORK - A US lawmaker has called Pakistan a 'radical Islamic terrorist State, and backed a proposal that Washington work more closely with Russia to end the conflict in Afghanistan. In a letter published in The New York Times on Friday, Republican Congresswoman Dana Rohrabacher, who is the Chairman of the House Foreign Affairs Subcommittee on Oversight and Investigations, also called for ending US 'irrational relationship with Pakistan and strengthening of ties with India. Rohrabacher wrote the letter in support of two officials of an American think-tank who argued in a Times op-ed article that the US should work more closely with Russia in Afghanistan. 'They are right on target, she said. 'America must end its irrational relationship with Pakistan, which is clearly in cahoots with the insurgents we have been fighting. An American-Russian alignment based on opposition to Islamic extremism would provide a common interest to underpin a positive reset of relations, she said. 'We also need to shift our stance toward India on the same basis. New Delhi is a friend and a potential ally. India is a democracy with security interests in line with ours against Pakistan, she added. 'The writers argue that a northern route for Afghan supplies would be safer. It would also end the convoy-protection payments that NATO makes to Taliban-linked warlords, money that ends up buying weapons used against our troops in Afghanistan. This insanity must end, she said.
