The U.S. Is a Sitting Duck

Everyone, it seems, has angst about where the terrorists will strike next; airlines, ferries, tall buildings, drinking water, gas attacks--all the while not really concerned about our real vulnerablilities. For instance, oil refineries. Did you know that if 25 of our largest refineries were disabled that 37% of our gasoline, diesel, capacity would be knocked out. That would destroy the U.S., literally. It takes billions of dollars and years of construction to build a large refinery and if a few were knocked out that would have a catastrophic impact on the economy and our ability to function as a nation. Hard to do? Nope.
Twenty-five pickup trucks loaded with three to five men, with 3 to 4 of them handling RPGs loaded with Armor Piercing rounds and High Explosive rounds--one to puncture fractionation towers and storage tanks, the other to set off any oil or compounds that might not ignite right away--first drive up to the gate and blow it, then drive in to blow the place up--all within a few minutes.
Without oil the U.S. is a sitting duck.
Other targets may seem "scarey", but the real danger is a loss of oil, whether in depletion (we are down to 21 billion barrels--we use 7 billion a year) or destruction of our refineries. Even one or two destroyed would be devistating as many of our refineries service local or regional areas, which would be particularly devastating to a region and stressful to other regions as they try to make up the loss if a refinery or two would be lost.
Fortunately the terrorists lack real abilities to do us harm and sensible security measures have discouraged them from any large scale attack, but sloppy border control and a lack of cooperation from the Mexican government is a real threat to our security. If thousands of pounds of drugs can get across RPGs and terrorists can too.
