Unchecked immigration — the de facto policy under Obama – -poses a far greater threat to American security and preservation of culture than does ISIS, or any of its affiliates.

One of the many dangerous aspects of unchecked immigration is illegal immigration, and the American people know this. Thus Donald Trump — rejected by the GOP establishment — has been able to catapult his candidacy ahead of other GOP presidential hopefuls by seizing on two key issues: First, murders and other crimes committed by illegals, and secondly, a promise to secure the southern border.

High-profile crimes by illegals get everyone’s attention for a while, such as the murder of Kathryn Steinle allegedly by an illegal alien in the sanctuary city of San Francisco on July 1, but then the shock passes and politicians like House Minority Leader Nancy Pelosi (D-CA-12th) walk up to the microphone to tell us sanctuary cities and related policies are not the problem. Rather, private gun ownership is. Of course, Pelosi overlooks the fact that the illegal alien who allegedly shot Steinle had multiple felonies and had already been deported numerous times before shooting Steinle with a stolen gun.

The murder of Steinle got a lot of attention. But  how many crimes committed annually by illegals are never even reported, let alone get front page attention?

American Thinker pulled together numbers from the Government Accountability Office (GAO) which show “the number of criminal aliens in federal prisons in fiscal year 2010 was about 55,000.” And when you look at a completely different set of numbers — the number of incarcerated illegals in state prisons and sons and “local jails” — the number for 2009 was approximately 296,000. Many of these are not people incarcerated for petty offenses.

For example, after examining “data on criminal aliens incarcerated in federal prisons from fiscal years 2005 through 2010 and… data on criminal aliens incarcerated in state prisons and local jails from fiscal years 2003 thorough 2009,” the GAO reports that illegals committed 213,047 assaults, 115,045 burglaries, 69,929 sex offenses, 42,609 incidents of “property damage,” 25,064 homicides, and 14,788 kidnappings, among many other crimes and categories of crime.

Again: 25,064 murders by illegal immigrants, yet the mainstream media is largely silent and that keeps the template in place for lambasting individuals like Donald Trump and Ann Coulter when they point out the danger illegal immigration poses to Americans.

Coulter put the enormity of the illegal threat in perspective in her book, Adios America. She writes: “Is an American citizen more likely to to be murdered by a Muslim terrorist or by a Mexican? According to CNN, twenty-nine Americans have been killed in Islamic terrorist attacks on the United States since 9/11. I don’t know why they excluded 9/11, so by my count, it’s 3,029. In fact, let’s round it up to four thousand to cover the last several decades.” She then references GAO information on illegals and crime to show that the 3,029 Americans murdered by Islamists equal only one-eighth the number of Americans killed by illegal immigrants.

Yet America’s immigration problem is not just with illegals. The problem also includes the kinds of legal immigrants the current administration welcomes into our country.

Americans need to understand that too many legal immigrants from one region, country, or ethnicity which is opposes our historical norms cripples our country’s ability to have a future that stays faithful to our past. In this way, unchecked immigration can literally and quickly alter the course of America.

For example, the most recent Pew Research Center on gun control shows that 47 percent of Americans believe gun rights are more important than gun control, while 50 percent of Americans believe just the opposite, and another three percent say they just don’t know. Is it good that nearly half of all Americans value gun rights over gun control? Sure it is. But it won’t last long if America keeps drawing the majority of its immigrants from Mexico, and here’s why. The Pew poll shows that 57 percent of white Americans want the focus on gun rights, versus 40 percent who want the focus on gun control — while the vast majority of Hispanic respondents made clear they think gun control should be the focus.

Only 24 percent of Hispanics believe gun rights are more important, while 75 percent believe more gun control is needed.

How long until there are enough Hispanic immigrants in America to tip the scale so that the natural, God-given right to keep and bear arms is treated like just another privilege the government can regulate or curtail at will?

There are other problems. America is passing up on highly-educated intellectuals and professionals from European and other non-Muslim countries to bring in people more adept at menial tasks, like selling coffee or sandwiches, than inventing the next generation of automobile or passenger jet or discovering the next miracle drug. As Coulter deftly observes: “[America’s] official policy is to turn away astrophysicists in order to make room for illiterate Afghan peasants who will drop out of high school to make coffee carts until deciding to engage in jihad against us.”

Just look at Muslim immigration if you need your eyes opened to the danger we face. On August 20, American Thinker pointed out that Muslim immigration has increased 66 percent in the most recent decade since 9/11. And the projection is for a surge starting late this year and continuing through next year that will consist of Muslim immigrants from Syria.

Can this end well?

The current immigration policy and the United States as envisioned by our Founding Fathers are mutually exclusive. One of the two will win the day, but for that happen, one will have to crush the other. And currently, the unchecked flow of Third World immigrants taken instead of doctors and scientists, combined with illegals crossing our southern border at a startling rate, seem to be winning the day.

Trump says the border must be sealed. Coulter argues that all immigration must be re-examined so that we are welcoming the best and brightest, rather than those who couldn’t make it in their own country and decided to come here and take taxpayer benefits, or even worse, to actively wage war against it.
