The World's Policeman?

Should we be “the world’s policeman?” that depends on what the world does, doesn’t it? Bashitr Assad is murdering thousands of his own people in his effort to stay in power Ahmadinijerk is talking about “pushing Israel into the sea” while working like a beaver to create his own nuclear bomb with which to do it. N. Korea has nuclear capability and is run, like Iran, by a madman. Russia is building their military at a breakneck pace while we look the other way since “communism failed” there. But DID it? Notice the same people who were in power when it was a communist nation are STILL in power today. They just SAY they're not communists any more. Their very leadership today were leaders in the old communist regime. DID communism fail? Or did they just rename it? They are STILL a socialist regime, and communism is but ONE kind of collectivism. Socialism is another. Both are based on stealing from those with the ABILITY to earn their own way for the benefit of those who AREN’T. SHOULD we be “the world’s policeman?” Somebody has to. We’re the biggest and most powerful (so far). Why not? What if communist China was "the world's policeman?" (The Guardian/Michael Tomasky)
