In March, Hillary Clinton assured us, “I think we’ve done a really good job securing the border. I think that those who say we haven’t are not paying attention to everything that was done the last 15 years under President Bush and President Obama.” That same month, Barack Obama declared the Islamic State is “not an existential threat to us.” Joe Biden echoed that statement this week, telling The Atlantic, “Terrorism is a real threat, but it’s not an existential threat to the existence of the United States of America.” Democrats keep telling us we have nothing to worry about. But the facts tell us otherwise.

Army Col. Lisa A. Garcia, a representative of the U.S. Southern Command, just revealed, “Networks that specialize in smuggling individuals from regions of terrorist concern, mainly from the Afghanistan-Pakistan region, the Middle East, and East Africa, are indeed a concern for SOUTHCOM and other interagency security partners who support our country’s national security.” Alarmingly, she added, “In 2015, we saw a total of 331,000 migrants enter the southwestern border between the U.S. and Mexico, [and] of that we estimate more than 30,000 of those were from countries of terrorist concern [emphasis added].”

To give this perspective, consider that a remarkable 11% of last year’s border-crossers are reasonably suspected by counterterrorism officials of being affiliated with militant groups. The fact that some 30,000 individuals — those who the Obama administration would deceptively call “lone wolves” — entered the country last year to possibly plot attacks is concrete evidence that we are not doing “a really good job securing the border.”
