Further on Dr. Hanson’s excellent points, I would note that when open borders advocates argue that, of the millions of illegal entrants, there is no evidence of jihadists crossing into the U.S. from Mexico, this simply is not so.

In March of 2006, FBI Director Robert Mueller testified before a House committee that the Bureau had broken up a Hezbollah smuggling ring that had succeeded in infiltrating jihadists into the U.S. through Mexico. As NewsMax reported at the time:

FBI Director Robert Mueller said this week that his agency busted a smuggling ring organized by the terrorist group Hezbollah that had operatives cross the Mexican border to carry out possible terrorist attacks inside the U.S.
“This was an occasion in which Hezbollah operatives were assisting others with some association with Hezbollah in coming to the United States,” Mueller told a House Appropriations subcommittee during a Tuesday hearing on the FBI’s budget.
In a stunning revelation, Mueller admitted that Hezbollah had succeeded in smuggling some of its operatives across the border, telling the House committee: “That was an organization that we dismantled and identified those persons who had been smuggled in. And they have been addressed as well.” …

I continue to wonder whether the administration’s reluctance to deal more forcefully with Iranian provocations owes in part to concerns over the likely presence of Hezbollah operatives inside the United States.
