Economic sanctions COULD work...and Bibi Netanyahu believes that also.
The problem is....just like with Iraq, getting other countries to STOP supplying Iran.
We know that Hugo Chavez would sail a ship of fuel to Iran himself if he had to...just to stick it to the USA.
When my son was in Germany for World Cup he said there were many many young Iranians there waving the Iranian flag of the Shah. They are begging for help from the US to free that country from the economic disaster created by Imadamnutjob.
