It'll take another 9/11 kinda attack on US for them to realise what LeT is. Who knows if it is the US who is abetting terrorism under the garb of weapons trade. US has always been a war economy... Iraq was bombed for economic reasons... Everybody was convinced that Saddam didn't have even enough conventional ammunation, leave aside WMDs.
It was US who surrected the Mujahideens against USSR in Afganistan & now also they are doing the same by providing support to Pakistan - the terrorist school of the world. Hats off to Musharraf for his masterstroke of carrying on the so called "War on Terror" and simultaneously providing a backdoor shelter to Osama & Co.
