According to a U.S. army strategist:

"In sum, U.S. policy in the Middle East is confused, contradictory, counterproductive, and dangerous. It could leave Washington involved in a war with Iran. (And given our recent wars in the region, imagine where that’s likely to land us.)"

The worry is what would a war with Iran cost the U.S. Who cares of what would cost the Iranians? There are some interesting arguments though by this enlightened mind in the most dangerous imperialist army on earth.
