In the 1940s, politicians and the State Department saw the war ravaging Europe and said only Christians could enter this country as refugees, and only a select few at that. No Jews welcome here. A favorite argument for turning away Jews fleeing Europe was that somehow they had been infiltrated by Nazis.

With ISIS on the rampage and war devastating Syria, among other places, many politicians today are singing a similar tune. Only a select few refugees can come in, and they must all be Christians, say Ted Cruz and Jeb Bush.

“No Muslims welcome here” is the theme frequently invoked in the name of national security.

No Syrian refugees in my state, said 31 governors — all but one Republican — who refuse to admit any Syrian refugees, whichever god they worship. That includes Michigan Gov. Rick Snyder, Ohio’s John Kasich, New Jersey’s Chris Christie and Florida’s Rick Scott, whose states have some of the country’s largest populations of Muslims and Arab Americans.

Christie said not even “orphans under the age of 5 should be admitted.” Taking care of them would be too much of a burden, he complained.

American Jewish leaders are struggling with the question of refugees. Many organizations have been raising money for humanitarian groups helping Syrian refugees, but when it comes to admitting them to this country they urge caution.

Rabbi Mark Dratch of the Orthodox movement’s Rabbinical Council of America told the New York Jewish Week that Muslim countries should be pressured to take greater numbers. He’s right. Jordan and Turkey are overwhelmed with refugees, but the others could and should do a lot more.

But that does not mean our own doors should be slammed in their faces, and Jewish leaders, more than most, should know that.

HIAS, formerly the Hebrew Immigrant Aid Society, is virtually alone among Jewish organizations supporting the president’s decision to admit 10,000 refugees by the end of 2016.

Prime Minister Benjamin Netanyahu has said that although Israel has treated some 1,000 wounded Syrians, it will not take in any Syrian refugees because the country is “too small.” Opposition leader Yitzhak Herzog disagrees. “Jews cannot be indifferent while hundreds of thousands of refugees are looking for safe haven.”

Some Republicans who aspire to be the leader of the free world sound like bigoted xenophobes. Most conspicuous are ones whose own parents were refugees from brutal dictatorships or are married to immigrants.

Their rationale is that some jihadi terrorists may sneak in with the refugees (one apparently did in the French attacks), so all refugees should be banned.

Critics like to point to the 9/11 hijackers to justify anti-immigration attitudes. Sen. Marco Rubio (R-Fla.), who favored immigration reform before he was against it, said “some” of the hijackers “had overstayed [their] student visas.” Sen. Lindsay Graham (R-S.C.) has said all 19 were here on expired student visas.

Neither presidential wannabe did his homework. All 19 had entered the country legally; only one was on a student visa, which he did not overstay, and the others were on tourist or business visas, according to Factcheck.org.

The only Jew running for president, Sen. Bernie Sanders (D-Vt.), pledged to stand against Islamophobia and racism and backed President Obama’s decision to admit some 10,000 refugees. So have his two Democratic rivals, Hillary Rodham Clinton and Martin O’Malley, both of whom suggested raising the number to 65,000.

Rep. Steve Israel (D-NY) said, “We can protect our safety and our humanitarian values,” and we shouldn’t “slam the door on them.”

But that’s exactly what some Republicans want to do.

Alabama Sen. Jeff Sessions would shut down the government in order to keep them out. Presidential candidates Ben Carson and Mike Huckabee have written to Speaker Paul Ryan demanding he block all funding for Syrian refugee resettlement.

Donald Trump, warning that Syrian refugees could be ISIS’ “Trojan horse,” said if he were president he’d consider closing U.S. mosques with radical clerics and limiting civil liberties for all Americans.

Sen. Cruz, the son of a Cuban immigrant, said we should permit only Christian refugees because “there is no meaningful risk of Christians committing acts of terror.”

Has no one told Ted or Jeb about Dylann Storm Roof, who killed nine worshippers at the Emanuel AME church in Charleston, S.C.; neo-Nazi Frazier Glenn Miller, who got the death penalty last week for killing three people in Kansas he thought were Jews; Timothy McVeigh and Terry Nichols, who bombed the Alfred P. Murrah Federal Building in Oklahoma City; or the Unabomber?

Or how about those law-abiding folks of the Ku Klux Klan, the Aryan Nation, the Army of God and the Phineas Priesthood?

And what about the mass murders responsible for shootings at Newtown, Virginia Tech, Aurora, Centennial and Roseburg, to name only a few?

Ted and Jeb, there wasn’t a foreigner among them. No Muslims as far as I could learn. All “good” Christians.

President Obama said, “We don’t have religious tests to our compassion. That’s not who we are.” His compassion may not be tested, but the same is not true for many of those who want his job. And that should scare a Jewish community that remembers — or should — what it’s like to be shut out when the alternative is discrimination and maybe death.
