There is no substitute for armed marshals on every flight.
And there is no way to guarantee that somewhere, somehow, some "terrorist" or holy warrior (your choice) or some group of them will not penetrate security and complete their mission. The objective is minimizing the threat, not eradicating it. Risk can not be abolished from life. Even from American life.
So it's foolish for DEBKA to claim that the security measures "don't work." The evidence of their having worked in the past might very well be kept secret, for security reasons. DEBKA, of course, has an agenda, which includes provoking war between the U.S.A.. and the Islamic countries, any Islamic country. The bloodier the better. This can only benefit the Zio-Nazi cause they serve. Their agenda requires massive amounts of fear-mongering, such as: "Anti-Terror Measures Don't Work." Of course, if "anti-terror measures don't work," then the next logical step is to escalate, and escalation means sanctions, means, ultimately, invasion. The current objective is to move the U.S. at least one step closer to war.
The article is pure bullshit, nothing but nonsensical Zio-Nazi war-mongering propaganda and should be treated as such.
