Bud McFarlane served in the Marines and, years later, as President Reagan's national security adviser.

So I listened up when, at a Foundation for Defense of Democracies workshop on energy security, he said of Saudi Arabia's oil facilities: "Any self-respecting suicide-bomber could take them out. Any artillery man could do it, too."

Not only that: Two years ago, Mr. McFarlane wrote an article noting that al Qaeda terrorists had attempted to blow up a major Saudi oil-processing facility. Had the attack succeeded, he wrote, "it would have taken the terminal off line for weeks if not months and raised the price of oil to more than $150 per barrel."

The price of oil today is nearing that level anyway. So just imagine what a terrorist attack on the global oil supply network would mean now. Mr. McFarlane articulated it clearly: "If oil flows from the Persian Gulf were disrupted [as al Qaeda has promised and which could easily happen], we would see oil at more than $200 per barrel overnight. ... The global economy would likely fall into deep depression."

You would think politicians would be making it a top priority to ensure against such a dire possibility. You would think the presidential candidates would be seriously debating policies that could protect us should this strategic commodity - lifeblood of our economy, essential to our military - stop flowing or continue to soar in price. But you would think wrong.

The slogan on Newt Gingrich's www.AmericanSolutions.com Web site: "Drill here. Drill Now. Pay Less." Certainly, it makes sense to tap America's proven energy reserves and, as Mr. Gingrich says, "reduce our dependence on foreign energy sources from unstable countries."

In early 2001, I was an adviser to Interior Secretary Gail Norton. Using energy resources in Alaska and off our coasts - while scrupulously protecting the environment - was among her top priorities. But even with a Republican in the White House and a Republican majority in both houses of Congress, she could not get the job done.

Now Democrats control Congress and most of them continue to oppose drilling just about everywhere. If they were to change their minds tomorrow, it would have an impact on the futures market, but it would be years before you could fill your tank with gas from new American sources.

The fastest way to begin protecting ourselves from supply disruptions and price hikes: Congress could establish an Open Fuel Standard, requiring that every automobile sold in America be capable of burning a variety of liquid fuels. The technology already exists and the cost is only about $100 per vehicle.

The prospect of many Flexible Fuel Vehicles (FFVs) coming into the market would provide an enormous incentive to entrepreneurs to compete for consumers' dollars by producing alternative fuels more abundantly and more rapidly. (Leveling the playing field among fuel-makers also should be on Congress' to-do list.)

If incentives for automobile manufacturers are required to open up the fuel market to competitive forces, provide them. Consumers, too, should be encouraged to trade in their old, high-polluting, mono-fuel vehicles for FFVs.

Mr. Gingrich has pointed out that the government - not least the military - drinks oceans of oil. Creating a free and competitive fuel market could bring the price of that oil back down to $90, $70 or even $50 a barrel. That would translate into enormous savings - enough to pay for the incentives.

Longer term: Accelerate the production of both plug-in hybrid and pure electric cars. In America today, we've just about stopped burning oil to generate electricity. In America tomorrow, we should use nuclear, coal, wind and solar power to make more electricity and give Americans additional transportation choices.

Plug-in hybrids have flexible fuel engines that power the car when it would be inconvenient to re-charge the battery by plugging into a wall socket. Pure electric cars may have engines that simply recharge the battery when you can't plug in.

There is more that can be done, but by starting with the policies outlined above, foreign oil can be stripped of its strategic status. Terrorists targeting oil facilities in Saudi Arabia would no longer be a major concern. Iranian mullahs couldn't threaten to cut off exports to teach Americans a lesson - as Iranian Supreme Leader Ali Khamenei did just this week. The price of fuels will be determined - and disciplined - by market forces in a competitive environment.

Less money will end up in the hands of terrorists. And the mobility we Americans prize will not be sacrificed. If the politicians you've sent to Washington have a better way to ensure our future, by all means let's hear about it.
