“It’s time we talked about regime change in North Korea – and I do not mean military action – but I do believe that this is a very unstable regime,” McCain told Candy Crowley Sunday on CNN’s “State of the Union.”…

“The key to this, obviously, is China and, unfortunately,China is not behaving as a responsible world power,” McCain said. “It cannot be in China’s interest in seeing a renewed conflict on the Korean peninsula.. We’ve got to understand that China is not what we want it to be, but is not playing a responsible role on the world stage, much less on the Korean peninsula. They could bring the North Korean economy to its knees if they wanted to and I cannot believe that the Chinese should, in a mature fashion, not find it in their interest to restrain North Korean – and so far hey have not.”
