What to do about Iran

The U.S. is heading down a dangerous path by making hostile gestures towards Iran. The means to defanging Iran is not by waging war but by taking away its source of political power. Iran depends on large part on its oil revenue and high oil prices gives Iran the money by which it can do things; like building nuclear programs, sponsoring terror, buying "friends" and weapons. By going the hostile route with Iran we would just fall into a trap from which we would find it very difficult to extract ourselves from.
The answer to the Middle East problem is to use alternative fuels; such as biodiesel, ethanol, and syngas. We have to go that route fairly soon anyway so why not now propose and implement a plan to make it mandatory that in five years 50% of our fuel consumption would be by alternative fuels. That would take a lot of the power away from the Middle East, and elsewhere, reduce oil prices, and build up a much needed alternative energy infrastructure.
By not going this route, competition for a depleting fuel source will increase, prices will go higher and higher, we will have to spend more on the military, and diplomatic relations will go into the can.
As it is countries, importing oil to the U.S. and to our allies, have us all over an oil barrel from which there is no removing ourselves from.
