War with Iran would likely be a disaster

"As America started up the road to Baghdad in 2003, Gen. David Petraeus is said to have asked, 'Tell me how this ends.' Before some agent provocateur pushes us into war with Iran, Congress should debate the wisdom of authorizing President Obama, or anyone else, to take America into her fifth war in a generation in the Middle and Near East."  So advises Pat Buchanan in this article over at the American Conservative:  Who Wants War with Iran?  As tensions in the Persian Gulf increase, it would do well for policy-makers to pay attention to the consequences of engaging Iran militarily.  Buchanan's op-ed serves as a good introduction to the complexities and the likely negative consequences that would flow from a military attack on the Iranians.
