Produce more and become stronger economically. Strength of a nation ultimately flows from its economic power which flows from its people.
Start building nuclear power plants and generate plentiful cheap electricity. Lower energy costs lowers the cost of everything we produce while at the same time increases our standard of living. That makes us stronger.
In addition with cheap plentiful electricity electric cars will find their way into many homes lowering our demand for oil. Lowering our demand for oil has two big benefits and one big negative... The two up sides are breaking our dependence of foreign countries for oil and stopping the funding of our enemies. The big downside is, if our demand for oil dropped significantly, world prices for oil would collapse. If the price of oil collapses then our competitors that use that oil will have even cheaper energy... And electric cars have to then be able to compete with cheap gas powered cars using cheap gas - and then the oil dependency cycle starts all over again...
Virtuous cycle vs vicious cycle.
Though after diversification, through plentiful electric energy and flex-fuel cars (which, unfortunately, are at least a decade away), oil “shocks” should be much milder, unless we get ourselves into a “conservation” of energy mode again... because we use 25% of world’s energy and all...
