If you can take it elsewhere, I'm no fan of the CPC, but united action is required to meet the challenge and the challenge is coming from the initiative of the people themselves unleashed by capitalism and backed by mercantilist policy. They are more an economic threat than a military one, they have little interest in military conquest, that road lies in economic dominance.
They are not a liberal democracy and are a threat to it, but of a different kind. In the end their own corruption will bring them down, it's bad enough here with a free press and elections to act as a check.
