There is no "Jewish lobby" in the US.... Nor are Jews in general particularly adept at either security or defense, at least no more so than any other group of people...
Anyone with familiarity of things like Krav Maga, or who saw locked-and-hardened El Al Israel airline cockpits starting in the 1970s might disagree.
Israelis have agents that talk to people waiting in line to get to the El Al airline counter to size up passengers. Their version of the TSA looks for bombers, not bombs.
