Imagine if the US government diverted the billions spent on this war into building out green energy infrastructure.

If everyone had electric cars charging from solar then Iran's strait gambit would be much less effective.

American citizens have known since 1973 that their dependence on oil puts them at the mercy of every Middle East dictator. The governments have known this clearly since the 1940s - see the Barbarossa operation. The US had literal generations to reduce their oil dependency and yet chose to remain dependent. It has nothing to do with the current war.
