Kissinger Warns Europe Its Open Borders Were ‘Grave Mistake’

America’s ongoing immigration crisis has sparked impassioned calls for action from Americans across the ideological spectrum due to the strain on resources, increased crime, and drug trafficking related to the porous southern border.

In light of the recent attack on Israel and subsequent demonstrations in support of the Hamas terrorists who perpetrated it, however, the immigration issue has taken on a new sense of immediacy.

The problem is even more acute in certain regions of Europe, where countries have opened up their borders for a massive influx of migrants in recent years. Now, former U.S. Secretary of State Henry Kissinger is sounding the alarm about the possibility that additional acts of terror will take place on that continent due to the permissive immigration policies.

During an interview with Politico, he advised that it was a “grave mistake” for European leaders to welcome so many migrants “of totally different culture and religion,” asserting that they should view the attack on Israel as a sign of things to come.

There have been a number of public pro-Hamas demonstrations across Europe since last week’s attack, which Kissinger chalked up to the “pressure groups” created when nations allow large numbers of culturally unassimilated migrants to enter.

In order to protect their own interests, he asserted that European nations should respond to the ongoing situation with “unconditional political support for Israeli action,” thus ensuring that Israel can “vindicate its sovereignty” and cool the tensions in Gaza.

“I would say every European nation has the same interest because the same attitude might erupt in the direction of Europe,” Kissinger said.

His recent warning serves as a departure from his stance in a 2015 letter to Congress as ISIS terrorists threatened attacks around the world. In it, he urged the U.S. to welcome Muslim immigrants because refusing to do so “only feeds the narrative of ISIS that there is a war between Islam and the West, that Muslims are not welcome in the United States and Europe, and that the ISIS caliphate is their true home.”

Hamas has made it clear that its violent ambitions are not limited to Israel. Earlier this week, a former leader of the terrorist group called on like-minded individuals to express their “rage” in communities around the world.
