Among the benefits of Donald Trump's proposed immigration moratorium is that we won't have to keep importing hordes of Third World "refugees," such as the ones currently swarming across Europe.

For decades, the United States has taken in far more refugees than the entire rest of the world combined. Nearly half of the refugees we take in are Muslim.

And it's worked out great!

Fazliddin Kurbanov, or "Idaho man," as he is dutifully described in the American media, was brought to the U.S. as a refugee in 2009, joining hundreds of other Uzbeks in Boise, Idaho. He came with his wife and young child, his sister and his two ailing parents. (What an economic powerhouse that family must be. Marco Rubio is right: We're making all kinds of money off of immigrants!)

So grateful was Kurbanov to America for rescuing his entire family from "persecution" that he spent the next few years conspiring to commit jihad against us.

As he cheerfully told his terrorist buddies back in Uzbekistan: "We are the closest ones to infidels. We have almost everything. What would you say if, with the help of God, we implement a martyrdom act? ... There are military installations right here, targets, and vehicles are available as well."

Kurbanov had plenty of time on his hands to plot terrorist attacks in the U.S. because he was being supported by you, taxpayer. As the Lewiston Morning Tribune (Idaho) reported: He was "struggling" to find a job -- preferably something that involved either marketing or killing all the Jews.

Last month, Kurbanov was convicted of various terrorism charges, based on his possession of Tannerite, ammonium nitrate, bullets and aluminum powder, as well as his stated intention, in conversations recorded by the FBI, to bomb military bases in Idaho and Texas.

For the cherry on top, the whole welfare-dependent, Islamic terrorist-nurturing family won refugee status in America by claiming they were persecuted in Uzbekistan for being Christians.

I am 100 percent sure there will be no thought given to deporting the rest of this useless family. To the contrary, we're probably bringing in their cousins. You wouldn't want to separate families, would you?

A few years ago, the FBI realized we'd let in scores of Iraqi terrorists as "refugees," including Mohanad Shareef Hammadi and Waad Ramadan Alwan -- the latter of whose fingerprints were found on boxes of IEDs seized in Iraq. On FBI surveillance tapes, the men bragged about having used a sniper rifle to kill American soldiers north of Baghdad, blowing up Bradley tanks and building more than a dozen bombs for use against U.S. troops.

After being happily "resettled" into public housing in Bowling Green, Kentucky, they continued their war against America, including one specific Army captain. Soldiers who had survived an IED attack that killed four troops in Iraq were warned by the FBI that their comrades' murderers had been relocated to America -- courtesy of the U.S. government -- and might be coming for them.

The Boston Marathon bombers, Tamerlan and Dzhokhar Tsarnaev, had received asylum in the U.S., before launching the 2013 attacks that left four dead and thousands injured in Boston. That's not including the three Jewish men whose throats Tamerlan slit in Waltham, Massachusetts, a few years earlier.

The entire extended Tsarnaev family got asylum based on Russia's brutal crackdown on Chechnyan Muslims -- persecution so unspeakable that various family members continued to vacation there.

Hundreds of "refugees" from Somalia and elsewhere, who have been granted fast-track U.S. citizenship because of their sworn fear of persecution in their home countries, seem to forget all about that "credible fear" as soon as the time comes to go back and engage in jihad.

To be sure, not all our beloved refugees are Muslim terrorists. Some are Hutu terrorists. A few years ago, we took in a genocidal Rwandan, Beatrice Munyenyezi, as a "refugee."

Only after Munyenyezi was granted citizenship did we find out that, as the federal court put it, she had "personally participated in the mass killing of innocent women, men and children merely because they were called Tutsi."

Although her American citizenship was revoked, Munyenyezi remains a legal U.S. resident, whom we are supporting in prison for the next decade. Only an immigration court can order her deportation. Which it will not.

A few other heart-warming humanitarian stories:

-- Sheikh Omar Abdel-Rahman, or "the Blind Sheik," imprisoned for life in the U.S. for his participation in the 1993 World Trade Center bombing: Asylee.

-- Ramzi Yousef, ringleader of the 1993 World Trade Center bombing: Asylee.

-- Egyptian Hesham Mohamed Hadayet, who shot up the El Al ticket counter at the Los Angeles airport, killing two: Refugee.

And the list goes on ...

Even the refugees who don't specifically come here to murder Americans aren't fleeing persecution. They're fleeing countries with less generous welfare policies than we have in the West. Which won't exist anymore, if we don't turn off the spigot from the Third World.

For at least half a century, the U.S. has taken in the vast majority of the world's refugees. Isn't it somebody else's turn, now?

How about Mexico take in a few "refugees"? Why not El Salvador or Honduras? Could the pope have a word with his co-religionists about the suffering in Syria? How about Vatican City? Talk about the perfect place to build some low-income housing projects!

Maybe it's time the world gets used to life without the United States. If our current immigration policies aren't stopped, this country will soon be nothing more than another failed Latin American state.

Speaking of which, I note that our allies, Japan and Israel, aren't taking in any Syrian refugees. Japan is pretty far away, but Israel is even closer to Syria than Sweden is! Evidently, Japan and Israel aren't as gung-ho about destroying themselves as our European friends are. Donald Trump's soaring popularity suggests that America may not be ready to commit suicide yet, either.
