Is subjecting "foreign" passengers to extra screening a valid air security tool?

I was illustrating the real and current existence of “people who want to blow up planes” (i.e. Al Qaeda tendency radicals, who want to “do jihad”) who also happen to be non-brown, have Anglo Saxon names, and have US passports.

Unfortunately the inference you draw is unsupported by evidence and, basically, crapola.

A father, his two sons and four other North Carolina men are accused of military-style training at home and plotting “violent jihad” through a series of terror attacks abroad, federal authorities said Monday.

An indictment released Monday does not detail any specific terrorist plans or targets overseas, although it claims some of the defendants traveled to Israel in 2007 with the intent of waging “violent jihad” and returned home without success.
