Not the same proof that the indians provided before May 1998 that Pakistan has absolutely no nuclear weapons and can never possess them. If Pakistan did provide evidence of it's h-bomb and thermonuclear weapons capability or it's long range missile capability than it's economy would be destroyed by the west. Take a hint, why the sudden and intense pressure by the americans to halt Pakistan's nuclear and missile programs? Why didn't india attack Pakistan in 2002 or 2008 even when the americans were indirectly encouraging the indians to do so? Even when india's military is supposed to be 10x more powerful than Pakistan's.
