Fareed Zakaria on why declaring war on Iran is a Very Bad Idea (tm).
The United States is being asked to launch a military invasion of a state that poses no imminent threat to America, without sanction from any international body and with few governments willing to publicly endorse such an action. Al-Qaeda and its ilk would present it as the third American invasion of a Muslim nation in a decade, proof positive that the United States is engaged in a war of civilizations. Moderate Arab states and Muslim governments everywhere would be on the defensive. And as Washington has surely come to realize, wars unleash forces that cannot be predicted or controlled.
