Victor Davis Hanson on threats of the future:

It would be naïve of us to think that a Venezuela, a Saudi Arabia, or an Iran will ever unite with us to stop such terror, when the direct result of such uncertainty is an enhanced position for their regimes and cash windfalls in the tens of billions of dollars. We should assume instead that within a year or two we may well see a series of coordinated attacks on Russian or Middle Eastern petroleum facilities and tankers, as well as efforts to knock out or flip over a large exporting country; and we should plan right now for that eventuality. Greater fuel efficiency of our cars coupled with careful drilling in the Arctic is the obvious compromise, along with more nuclear power and continued work on hybrid fuels.
