After the 9/11 attacks, when 19 Muslim terrorists — 15 from Saudi Arabia, two from the United Arab Emirates, and one each from Egypt and Lebanon, 14 with “al” in their names — took over commercial aircraft with box-cutters, the government banned sharp objects from planes.

Airport security began confiscating little old ladies’ knitting needles and breaking the mouse-sized nail files off of passengers’ nail clippers. Surprisingly, no decrease in the number of hijacking attempts by little old ladies and manicurists was noted.

After another Muslim terrorist, Richard Reid, AKA Tariq Raja, AKA Abdel Rahim, AKA Abdul Raheem, AKA Abu Ibrahim, AKA Sammy Cohen (which was only his eHarmony alias), tried to blow up a commercial aircraft with explosive-laden sneakers, the government prohibited more than 3 ounces of liquid from being carried on airplanes.

All passengers were required to take off their shoes for special security screening, which did not thwart a single terrorist attack, but made airport security checkpoints a lot smellier.

After Muslim terrorist Umar Farouk Abdulmutallab of Nigeria tried to detonate explosive material in his underwear over Detroit last Christmas, the government began requiring nude body scans at airports.

The machines, which cannot detect chemicals or plastic, would not have caught the diaper bomber. So, again, no hijackers were stopped, but being able to see passengers in the nude boosted the morale of airport security personnel by 22 percent.

After explosives were inserted in two ink cartridges and placed on a plane headed to the United States from the Muslim nation of Yemen, the government banned printer cartridges from all domestic flights, resulting in no improvement in airport security, while requiring ink cartridges who traveled to take Amtrak.

So when the next Muslim terrorist, probably named Abdul Ahmed al Shehri, places explosives in his anal cavity, what is the government going to require then? (If you’re looking for a good investment opportunity, might I suggest rubber gloves?)

Last year, a Muslim attempting to murder Prince Mohammed bin Nayef of Saudi Arabia blew himself up with a bomb stuck up his anus. Fortunately, this didn’t happen near an airport, or Homeland Security Secretary Janet Napolitano would now be requiring full body cavity searches to fly.

You can’t stop a terrorist attack by searching for the explosives any more than you can stop crime by taking away everyone’s guns.

In the 1970s, liberal ideas on crime swept the country. Gun owners were treated like criminals while actual criminals were coddled and released. If only we treated criminals with dignity and respect and showed them the system was fair, liberals told us, criminals would reward us with good behavior.

As is now well known, crime exploded in the ’70s. It took decades of conservative law-and-order policies to get crime back to near-1950s levels.

It’s similarly pointless to treat all Americans as if they’re potential terrorists while trying to find and confiscate anything that could be used as a weapon. We can’t search all passengers for explosives because Muslims stick explosives up their anuses. (Talk about jobs Americans just won’t do.)

You have to search for the terrorists.

Fortunately, that’s the one advantage we have in this war. In a lucky stroke, all the terrorists are swarthy, foreign-born, Muslim males. (Think: “Guys Madonna would date.”)

This would give us a major leg up — if only the country weren’t insane.

Is there any question that we’d be looking for Swedes if the 9/11 terrorists, the shoe bomber, the diaper bomber and the printer cartridge bomber had all been Swedish? If the Irish Republican Army were bombing our planes, wouldn’t we be looking for people with Irish surnames and an Irish appearance?

Only because the terrorists are Muslims do we pretend not to notice who keeps trying to blow up our planes.

It would be harder to find Swedes or Irish boarding commercial airliners in the U.S. than Muslims. Swarthy foreigners stand out like a sore thumb in an airport. The American domestic flying population is remarkably homogeneous. An airport is not a Sears department store.

Only about a third of all Americans flew even once in the last year, and only 7 percent took more than four round trips. The majority of airline passengers are middle-aged, middle-class, white businessmen with about a million frequent flier miles. I’d wager that more than 90 percent of domestic air travelers were born in the U.S.

If the government did nothing more than have a five-minute conversation with the one passenger per flight born outside the U.S., you’d need 90 percent fewer Transportation Security Administration agents and airlines would be far safer than they are now.

Instead, Napolitano just keeps ordering more invasive searches of all passengers, without exception — except members of Congress and government officials, who get VIP treatment, so they never know what she’s doing to the rest of us.

Two weeks ago, Napolitano ordered TSA agents to start groping women’s breasts and all passengers’ genitalia — children, nuns and rape victims, everyone except government officials and members of Congress. (Which is weird because Dennis Kucinich would like it.)

“Please have your genitalia out and ready to be fondled when you approach the security checkpoint.”

This is the punishment for refusing the nude body scan for passengers who don’t want to appear nude on live video or are worried about the skin cancer risk of the machines — risks acknowledged by the very Johns Hopkins study touted by the government.

It is becoming increasingly obvious that we need to keep the government as far away from airport security as possible, and not only because Janet Napolitano did her graduate work in North Korea.
