When I look at long-term trends, it looks like fewer people are coming in, not more, and by quite a lot. The short term blips in the last few years are a drop in the bucket compared to the long-term downward trend.

Another claim I hear is that thousands of terrorists are getting in via the Southwest border and a wall would stop that. But this also looks like a blatant lie.
Nick Rasmussen says no such crisis exists.
Our federal courthouses and prisons are not filled with terrorists we’ve captured at the border. There is no wave of terrorist operatives waiting to cross overland into the United States. It simply isn’t true. Anyone in authority using this argument to bolster support for building the wall or any other physical barrier along the southern border is most likely guilty of fear mongering and willfully misleading the American people.
Why do I know this? As Director of the National Counterterrorism Center (NCTC) from December 2014 until December 2017, it was my job to lead the government’s efforts to collect and analyze all available information about terrorist threats to the Homeland. It was my responsibility on behalf of the Intelligence Community to synthesize and present that terrorism picture to our most senior decision makers – up to and including the President of the United States — so that sound decisions could be made about how to protect the Homeland from terrorist attack.
Here is ground truth on this issue. Terrorist groups like al-Qa’ida and ISIS spend time talking about, brainstorming and even fantasizing about ways in which they can do harm to the United State. At times, those conversations have certainly included discussion of ways in which terrorist operatives might be inserted into the Homeland. But we also knew from intelligence reporting that terrorist groups have very high regard for our Homeland Security capabilities, including our border security. They know we had become a much “harder” target than at the time of 9/11 and that getting their operatives into the United States is an extremely challenging proposition.
In part, that’s why terrorist groups pivoted in recent years to a different business model. Rather than focusing on trying to insert a terrorist operative from abroad, it has proven to be far easier for an organization like ISIS or al-Qa’ida to inspire or motivate an individual already inside the United States to act on their behalf. That change has left us with the threat condition that prevails today, in which the greatest terrorism threat we face is from what we call Homegrown Violent Extremists (HVEs) – in most cases individuals who were either born here or have lived here for most of their adult lives.
So ... is there a security crisis at the Southwest border? If so, can someone explain to me what it is?So, what to make of these thousands of so-called terrorists prevented from entering the country across our southern border? Where do these numbers come from? What seems true is that our system of terrorist watch listing is in fact working. Though DHS has not provided data to support its claims, I suspect that on many occasions in recent years, perhaps adding up to thousands, individuals who live abroad and want to travel to the United States have been denied the opportunity to do so because of a concern about a potential nexus to terrorism. Such an individual would have their visa or ESTA application denied and no travel would occur. In other cases, so-called Special Interest Aliens (SIA) from countries of terrorism concern have likely been stopped at the border.
But each of those visa denials or SIA encounters hardly equates to disruption of a terrorist plot or the “capture” of a known terrorist. Our watchlisting system is predicated on a carefully calibrated risk management approach. When the intelligence community acquires information that points to a potential link to terrorist activity, individuals are not permitted to travel to the United States.
