Donald Trump has dug in on The Wall. He wants it built and he wants you and me to pay for it, not Mexico — as he had pledged during his campaign for the presidency.

As a result, part of the federal government has shut down. Trump says the shutdown is needed to bolster — ostensibly — our national security. The Wall would protect us from those hordes of killers, rapists and sex traffickers seeking illegal entry into the United States of America.

Oh, but what about national security.

Airport security officers are working without pay. They’re calling in sick. The post-9/11 travel restrictions are suffering now because TSA agents aren’t showing up for work. Those who do are being put under undue stress while they wait for their next paycheck; they don’t know when that day will arrive.

And then we have our air traffic controllers. They are employed by the Federal Aviation Administration. The FAA cannot pay its air controllers, either.

Air traffic control is among the world’s most stressful of jobs even under the best of circumstances. As the head of the ATC union said this morning, those men and women have to be “100 percent 100 percent of the time.” Given the shuttering of the government, they aren’t functioning at 100 percent. They are worried about their mortgage payments, their kids’ tuition, their utility bills, grocery bills, car payments, credit cards payments. You name it, they’re stressing out.

Can these individuals spare a single moment away from their job of guiding airplanes, preventing jetliners full of travelers from crashing into each other? Of course not!

National security, Mr. President? You’ve got to be kidding — but you’re not.

Do you, dear reader, feel safer now? Me neither.
