By claiming that its war is similar to earlier U.S. struggles against Nazism and then Stalinism (while ignoring the fact that both Nazi Germany and Soviet Russia were first-rate military powers, a status al-Qaeda neither has nor can achieve), the administration could be preparing the case for war with Iran. Such war would then plunge America into a protracted conflict spanning Iraq, Iran, Afghanistan and perhaps also Pakistan.
Such fear-mongering, reinforced by security entrepreneurs, the mass media and the entertainment industry, generates its own momentum. The terror entrepreneurs, usually described as experts on terrorism, are necessarily engaged in competition to justify their existence. Hence their task is to convince the public that it faces new threats. That puts a premium on the presentation of credible scenarios of ever-more-horrifying acts of violence, sometimes even with blueprints for their implementation.
