The documentary, The President, aired on the Rossiya One television network and was billed as a look back at the 15 years since Putin became the most powerful man in Russia. Among his most painful memories, Putin said, were two events associated with the aftermath of uprisings in the Northern Caucasus, which the Kremlin put down brutally in 1996 and again in 2000. In 2002, Chechen rebels seized a Moscow theater in an operation that wound up costing the lives of a large number of people when security services staged a rescue operation.
