There had never been a case of Ebola in the U.S. until a few months ago. Since then, thousands of people have died of the disease in Africa, and millions upon millions of dollars have been spent treating Ebola patients in the U.S. who acquired it there, one of whom has died.

But the Obama administration refuses to impose a travel ban.

This summer, the U.S. government imposed a travel ban on Israel simply to pressure Prime Minister Netanyahu into accepting a ceasefire agreement. But we can't put a travel restriction on countries where a contagious disease is raging.

It's becoming increasingly clear this is just another platform for Obama to demonstrate that we are citizens of the world. The entire Ebola issue is being discussed -- by our government, not the United Nations -- as if Liberians are indistinguishable from Americans, and U.S. taxpayers should be willing to pay whatever it takes to save them.

Maybe we should give them the vote, too! If Ebola was concentrated in Finland and Norway -- certainly Israel! -- we'd have had a travel ban on Day One.

The head of the Centers for Disease Control and Prevention, Dr. Tom Frieden, justifies Obama's refusal to prohibit flights originating in Ebola-plagued countries, saying, "A travel ban is not the right answer. It's simply not feasible to build a wall -- virtual or real -- around a community, city or country."

What is it with liberals living in gated communities always telling us that fences don't work? THAT'S WHAT A QUARANTINE IS.

At the congressional hearing on Ebola last week, Republicans repeatedly pressed the CDC representative, Dr. Toby Merlin, to explain why Obama refuses to impose a travel ban.

In about 17 tries, Merlin came up with no plausible answer. Like Frieden, Merlin kept insisting that "the only way to protect Americans" is to end the epidemic in Africa.

Why, precisely, must we attack Ebola in Africa? Research on a cure doesn't require cuddling victims in their huts. Scientists who discovered the AIDS cocktail didn't spend their nights at Studio 54 in order to "fight the disease at its source."

Until there's a treatment, we can't put out the disease there, or here. The only thing Americans will be doing in Liberia is changing the bedpans of victims, getting infected and bringing Ebola back to America. When there's a vaccine, we can mail it.

Naturally, Obama is sending troops from the 101st Airborne, the pride of our Army, to Liberia. Their general should resign in protest.

Merlin further explained the travel ban, saying that if West Africans can't fly to America, "that would cause the disease to grow in that area and spill over into other countries." So instead of infecting people in surrounding countries, our CDC wants them to come here and infect Americans.

But that won't happen because the government assures us there's nothing to worry about with Ebola. They've got it under control.

Unfortunately, everything the government says about this disease keeps being proved untrue -- usually within a matter of days.

They told us that you'd basically have to roll in an infected person's vomit to catch the disease. Then, nurses at two first-world hospitals in Spain and the U.S. contracted Ebola from patients.

With no evidence, the CDC simply announced that the nurses were not following proper "protocol." The disease didn't operate the way CDC said it would, so the hospitals must be lying.

The government told us that national quarantines won't work, but then they quarantine everyone with Ebola -- or who has been near someone with Ebola, such as an entire NBC crew. To me, this suggests that there's some value in keeping people who have been near Ebola away from people who have not.

Quite obviously, the only way to protect Americans is to prevent Ebola from coming here in the first place. The problem isn't that Ebola will leap across oceans to infect Americans; it's that Obama doesn't want to protect Americans.

At least he's only putting expendable Americans on the frontlines of the Ebola epidemic -- doctors, nurses, members of the 101st Airborne.

At the moment, more than 13,000 West Africans have travel visas to come to the U.S. Having just seen an Ebola-infected Liberian get $500,000 worth of free medical treatment in the U.S., the first thing any African who might have Ebola should do is get himself to America.

Of all the reasons people have for coming here -- welfare, drug-dealing, Medicare scams -- "I have Ebola and I'm going to die, otherwise" is surely one of the strongest. The entire continent of Africa now knows that this is a country that will happily spend half a million dollars on treating someone who just arrived -- and then berate itself for not doing enough.

Thomas Eric Duncan's family may be upset with his treatment, but they have to admit, the price was right. Medical bill: $0.00. Your next statement will arrive in 30 days.

And now we're going to have to let in entire families with Ebola, because the important thing is -- actually, I don't know why. It's some technical, scientific point about fences not working.

Republicans -- Americans -- have got to demand Frieden's resignation. If only we could demand Obama's.
