Those familiar with Lawrence Kudlow‘s views on immigration might be surprised to read his latest column at Human Events.

I know this is not my usual position. But this is a war. Therefore I have come to believe there should be no immigration or visa waivers until the U.S. adopts a completely new system to stop radical Islamic terrorists from entering the country. A wartime lockdown. And a big change in my thinking.

ISIS and related Islamic terrorists are already here. More are coming. We must stop them

Until FBI director James Comey gives us the green light, I say seal the borders.

Here’s what we must do: Completely reform the vetting process for immigrants and foreign visitors. Change the screening process. Come up with a new visa-application review process. Stop this nonsense of marriage-visa fraud. And in the meantime, seal the borders. …

… Again, why am I taking this hardline position? In the past I have been an immigration reformer, not a restrictionist. But we are at war. That changes everything.

Let me emphasize that my support for wartime immigration restrictions is not based on religion. I think Donald Trump made a big mistake here. Instead, I agree with this Rupert Murdoch tweet: “Complete refugee pause to fix vetting makes sense.” …

… I say seal the borders. People hoping to relocate to the U.S. from Syria, Iraq, and anywhere in the Middle East, and people coming here from France, England, Sweden, and wherever will be upset, at least for a while. There may be some unfairness to this. But I don’t care. Wars breed unfairness, just as they breed collateral damage.

We may set back tourism. We may anger Saudi princes whose kids are in American schools. But so be it. We need a wartime footing if we are going to protect the American homeland.

Of course, President Obama doesn’t get it. He never will.
