The torrid pace of Muslim migration into the United States should be sending off alarm bells in the nation's Jewish community, but so far it has barely registered as the sound of a pin dropping.

The U.S. issued approximately 680,000 green cards to migrants from 49 Muslim-majority nations, as identified by Pew Research Center, in the five-year period from fiscal years 2009-2013, a figure that should be a red flag to American Jews.

There are only about 5.7 million Jews living in America. The Muslim demographic is estimated at about 3 million but is growing much faster due to immigration and the high fertility rates of Muslim women.

By comparison over the same five-year period under President Obama, the U.S. issued only about 270,000 green cards to Europeans. A green card is highly coveted because it allows the holder to access welfare benefits, lifetime residency, work authorization and a fast track to U.S. citizenship.

Among those receiving green cards are foreign nationals admitted to the U.S. as refugees, who must apply for adjustment to green-card status within one year of their arrival in the U.S. Refugees have immediate access to state and federal welfare benefits, such as Temporary Assistance to Needy Families or TANF, food stamps and Medicaid.

"Assuming no change in immigration policies, the U.S. can expect to grant green cards to at least another 680,000 migrants from Muslim-majority nations over the next five years," said a statement issued Thursday by Sen. Jeff Sessions' office. "The numbers, however, could be higher still: Census Bureau data shows migration from the Middle East to be one of the fastest-growing categories."

Nobody is watching, but the ramifications could be huge, says Laurie Cardoza Moore, president of Proclaiming Justice to the Nations at PJIN.org, a pro-Israel Christian organization.

To get a glimpse of their future, Jewish Americans only need to look across the Atlantic at Europe, where Muslim immigration has led to almost daily attacks on synagogues, Jewish cemeteries, schools and other Jewish properties, not to mention the attacks on Jewish people such as at the massacre at the kosher store in Paris on the day of the Charlie Hebdo attacks last year.

"If we look at what's happening in Europe, I think that's a good barometer of what we can expect to happen here in the U.S.," Moore said. "My concern about this whole Islamic migration into Europe and into the U.S. is that we did a tremendous disservice to these Muslims. If the real goal is the well-being of women and children, then why did the West take these migrants who are Muslim – their culture is completely different than Western culture – and why didn't the leaders of the free world go to the leaders of the Muslim world and say, 'Listen, your people are in trouble. Why don't you open up your doors and let them in?'"

An immigration policy gone awry

President Obama's refugee plan boosts the annual number of Mideast migrants admitted to the U.S. They, in turn, will be able to petition for their relatives to join them to the U.S. under the federal government's "family reunification" program.

But there is another trend line developing – one that could prove ominous to Jewish Americans first, and ultimately Christians, too.

If the current federal policy continues, it will lead to the U.S. Muslim population overtaking that of the U.S. Jewish population within two decades, said a demographic researcher at the Center for Immigration Studies in Washington.

"It will probably be 20 years or so," said Steven Camarota, director of research for CIS.

The number of new Muslim immigrants coming to the U.S. is estimated at between 100,000 and 120,000 a year, with about 35 to 40 percent coming through the refugee ranks. That's 500,000 to 600,000 over five years because all of the 680,000 coming from Muslim-majority nations are not Muslims.

"Many folks from Muslim countries are not Muslim, as it's the non-Muslims who (also) leave," he said, from counties like Iran and Bhutan. Even from Muslim-dominated Iraq, 30 to 35 percent of the refugees have been Christian.

The other side of the coin is that Muslim immigrants who do come to the United States have very large families compared to native-born Americans.

"There are also births to immigrants and native-born Muslims and converts to consider," Camarota said. "But there are also deaths and return migration.

"Overall, I would guess 20-25 years," before the Muslim population eclipses the Jewish population in the United States.

80 percent of mosques preach hatred

Robert Spencer, author of the Jihad Watch blog at the David Horowitz Freedom Center, said four separate and independent studies since 1998 have found that 80 percent of mosques in the U.S. preach hatred of Jews and Christians and the need ultimately to impose Shariah law here.

As the Muslim population has grown, the number of mosques sprouting in the U.S. has multiplied by 15-fold since the Sept. 11, 2001, terrorist attacks that killed nearly 3,000 Americans, going from just 200 on 9/11 to between 2,500 and 3,000 today.

A 2011 study by Mordechai Kedar and David Yerushalmi found that only 19 percent of U.S. mosques preached no violence whatsoever.

The survey's findings were that 51 percent of mosques used texts that either advocated the use of violence in the pursuit of a Shariah-based political order or advocated violent jihad as a duty that should be of paramount importance to a Muslim; 30 percent had only texts that were moderately supportive of violence like the Tafsir Ibn Kathir and Fiqh as-Sunna; 19 percent had no violent texts at all.

This study followed others in 2005 and 2008 that found similar results.

"A lot of the material about the studies has been taken offline," Spencer told WND, to protect the guilty.

Moore said countries like Jordan and Lebanon are overrun with refugees while Saudi Arabia and the Gulf states have done nothing to relieve them of the burden.

"If you look in Europe, the majority of them are men of fighting age and should have been made to stay," she said. "But to absorb these men and leave the women and children behind makes no sense, so it makes you wonder about the real motive, is it really to help women and children or is there a hidden agenda here?"

Is end of Western civilization in sight?

Moore said the influx of 1.5 million migrants into Europe so far with another 3 million expected "poses a huge threat to the future of Western civilization."

And the same fate awaits the United States, which is taking in tens of thousands of Syrians, Somalis, Afghan, Burmese and Iraqi Muslims per year.

"It's unfortunately going to happen when more women and their daughters start getting raped and more people's heads are lopped off," she said. "Look at the number of honor killings that have occurred already in the United States over the last few years."

She described a case in Buffalo, New York, in which a female TV producer asked her husband for a divorce and he cut her head off in the studio.

Another girl in Texas was shot and killed at point-blank range by a male family member.

"Why? Because she was dating American boys."

Another case in Arizona involved a father running over his daughter with a car because she was dressing too Western.

"This is not going to just affect the Jewish community and Christian community," she said.

It will also affect Muslim women.

"They are governed by Shariah law where the laws of our country are supposed to protect them," she said. "It is the imams that are inciting this hatred in the mosques."

In a 2010 case near Murphreesboro, Tennessee, an imam was actively recruiting members to kill Jews in Israel.

"It's been going on, but it's going to become even more prevalent, what we saw in San Bernardino and in Garland, Texas, and at the Chattanooga recruiting center, and in Oklahoma City where the woman had her head cut off by a Muslim co-worker last year."

Moore said people who point out these atrocities will continue to be labeled "Islamaphobes."

"Of course, you can be anti-Christian and you can be anti-Semitic but you can't be anti-Islam," she said.

But Americans are starting to wake up, she said.

"I have had my busiest year ever with invitations to speak, and the one thing I am seeing is there are more people who are waking up and recognizing our communities are being threatened and people are rising up," she said. "We can win the battle and elect people to office who are going to protect our Judeo-Christian values quicker at the local level and state level. Washington will continue to be Washington."
