A national defense analyst warns the United States needs to thoroughly investigate refugees from Islamic countries if they're allowed to immigrate here.
Secretary of State John Kerry told members of Congress this week that the United States will boost its worldwide quota for resettling refugees from 70,000 to 75,000 next year.
Some of those refugees would be from war-torn Syria.
Kerry's announcement comes as European countries are struggling with tens of thousands of refugees from the Middle East flowing into Germany, Hungary, Greece and other countries.
"There's a ton of 20-something men who are going to be less than satisfied with life," advises Steven Bucci, a retired U.S. Army Special Forces colonel who directs the Allison Center for Foreign Policy Studies at The Heritage Foundation. "Well, these people could be radicalized."
Or they may already be terrorists. ISIS has openly bragged that it's exploiting the flood of refugees and sending fighters into Europe.
Islamic expert Robert Spencer warns the mass immigration is "hijrah," a migration meant to turn new territory into Islamic territory.
In Greece, Muslim refugees refused to accept free bottled water (see video below) due to the religious nature – it's from the Red Cross. A second video showed Muslim migrants chanting "Allahu Akbar" as they rode a train through France.
Bucci cites the example of Minneapolis, Minnesota, which has experienced troubles after allowing Somalis to settle there in the 1990s.
What has happened since? A story by NPR warned in a February that Minneapolis-St. Paul "is fast becoming the center of ISIS' recruitment effort in the United States."
In any large community, Bucci warns, it's not hard for just a few to "cause a lot of mischief."
