The throngs occupying Columbia’s manicured lawns aren’t there by chance. They are the ones whom the university, which boasts an admissions rate that hovers under 4 percent, had chosen. They are the ones the university had indoctrinated into hating Israel and the Jews. And they are the ones who are now simply doing what they’ve been for so long instructed to do. ...

Maybe it’s time to let Columbia, Yale, and other elite schools become what they already basically are: finishing  schools for the children of Chinese, Qatari, and other global elites. And let anyone interested in America’s future pursue education elsewhere. For some, this will mean applying to alternative institutions, like the University of Austin; for others, trade schools might offer a remunerative alternative. The undying American spirit of innovation will likely come up with more initiatives that cost less and offer much more than four years in an airless, ideological gulag.

It’s time we approached our elite universities not as critical institutions that we must repair but as national security threats that we must address forcefully. The message out of Columbia this week is that there’s nothing left on campus but fanatics awash in foreign funds, and fawned over by a faculty that long ago lost its decency, its courage, and its reason.
