Pakistan recently test-fired a nuclear-capable missile from an undisclosed location, for its short-range surface-to-surface Hatf-2 class rocket, which has been developed with help from China, Fox News reported. The US was the main supplier of weapons to Pakistan since the mid-1960s. But it began to back away from the deals after years of "difficult and sometimes unpredictable" relations following the 9/11 terror attack which led Pakistan to replace the US with China as a main source of defence material, at least in terms of arsenal, development and training.1
