Andrew Coyne has a fine, if depressing, column on the North Korea developments:
We simply do not have the stomach for this fight. We will learn no lessons from this latest crisis, as we have learned none from those before. But be assured our adversaries will. In Iran, they are watching and learning from North Korea's example, as North Korea had learned from Iran's, each discovering in its turn that there are no checks on its ambitions, nor any world to stop it. And when, as the wisest heads advise, we abandon Afghanistan to the Taliban, and Iraq to al-Qaeda, the nuclear bazaar really will be open.
