Pentagon acknowledges Scenario of Heavy Combat Casualties
It is common knowledge that a short victorious war usually raises the country’s leader’s popularity to the skies. The current US president needs this badly as his rating is rather low at present. However, a war against Iran is unlikely to be short and victorious. Iran is a much stronger enemy than Iraq or Afghanistan, where the wars have already lasted for 10 years. Incidentally, the US invaded Iraq on the same charges it is using against Iran now. No nuclear weapons have been discovered in Iraq, so Washington has to think again.
