1. Iran's atomic bomb-making and missile production are the direct result of ruthless and self-serving Chinese (PLA) proliferation.
1a. Following the successful containment of the Chinese anarchy of the 1980s, the PLA's concern was that it must prepare for the US response come the day the PLA moves to retake Taiwan. China's special sense of vulnerability was that the southeast of China, the industrial heartland, is vulnerable to US air strike, including nuclear weapon airstrike.
2. After the first Gulf War, Jiang Zemin and the PLA chose a policy to create multiple hotspots for the United States targeting, since the US nuclear warchest was locked into treaty limited production. China saw that every hotspot created outside of Russia and China was one more target away from the industrial heartland of China. Therefore, the PLA decision was to turn on proliferation. The first stage of the plan began with the Benazir Bhutto visit to China in 1993, when the transfers began into the hands of A.Q. Khan. An adjacent step was to transfer weapons technology to Kim Il Jung, the old man, in North Korea.
