There is still no evidence that Iran is trying to build nuclear weapons. Indeed, the body of evidence suggests the opposite, including the 2007 US National Intelligence Estimate that Tehran mothballed its program in 2003. But evidence is irrelevant when the enormous economic power of the United States and the EU can cow the rest of the world, and force a country to its knees without resorting to open hostilities.

In short, war by other means.
