Dr. Michael Pillsbury sat down with Mark Levin to discuss China's tactical maneuvers against the United States through its science, technological and military capabilities.

Pillsbury, director of the Center for Chinese Strategy for the Hudson Institute, was the Assistant Under Secretary of Defense for Policy Planning under President Reagan.

He said that during the Cold War, China secretly sold $2 billion worth of weapons to the United States that were then transferred to the Afghan rebels, forcing the Soviet Union into a "humiliating defeat."

"We discovered the Chinese were hawks against the Soviet Union," he said.

He said it was discovered that the Chinese were willing to use "aggressive efforts" like sniper rifles and commando raids inside the Soviet Union.

Pillsbury told Mark Levin that China also assisted the United States in Cambodia against the Vietnamese Army.

"The U.S. and several other countries ... got together with the Chinese Intelligence Service and provided weapons to the Cambodian resistance."

He said, though, that China showed itself as a fierce opponent of the Soviet Union through other project, leading to the belief that they would be pro-America.

"It turned out that was just a tactical move, that at that time the Soviets were their enemy as well as ours," Pillsbury said.

"But who would have thought later that they would see us as a rival for global leadership and turn on us?"
