About what a U.S. strike on Iran would mean:
1. Bombing a sovereign nation is a de facto declaration of war. Our Constitution requires the Congress, not the President, to declare war. Simply because we have launched a number of wars without a Congressional declaration does not mean the Constitutional requirement has been suspended;
2. Such an attack will have economic consequences for us. The Iranians most likely would blockade the Strait of Hormuz, thus reducing the shipment of Persian Gulf oil–almost one-quarter of our imports–and dramatically increasing world oil prices. This would have a powerfully negative affect on our already fragile economy;
3. Such an attack would place great stress on our military. We cannot continue the Afghan war, prop up the neighboring Iraqi government, and create a third battlefield in the Middle East. It is folly to assume that a US-Iran war can be carried out by the Navy and Air Force alone. Our ground combat forces are near exhaustion;
4. Bombing Iran would virtually assure an attack of considerable dimensions carried out against Israel. This would involve both Iranian and Lebanon-based missiles. Israel would necessarily retaliate. We would then have all-out war in the Middle East.
