Saturday, May 28, was the thirteenth anniversary of Pakistan’s first nuclear test in 1998. The day is known as Yaum-e-Takbeer, the Day of Revival. This year it revived a long-running and vicious campaign between the controversial Pakistani scientist Abdul Qadeer Khan and the former military dictator Pervez Musharraf, who in 2004 put Khan under house arrest, accusing him of proliferating nuclear secrets to Libya, Iran, and North Korea.
