With the very notable exception of 911, that&#x27;s simply not true.<p>The Madrid bombings, the various India and E. Africa attacks, the French attacks from earlier this year and yesterday-all of these could have been carried out with almost exactly the same with planning a century ago, or with ease a half century ago.<p>9&#x2F;11 was the only one of all those attacks that truly used technology in a new and frighteningly innovative way.  And almost <i>no one</i> thinks that will happen again, because every plane passenger in the world knows that unopposed Islamic radical hijackings are a death sentence, and so will without exception revolt en masse, even if it causes the plane to go down (indeed, there&#x27;s significant evidence that passengers had adapted to this terrifying reality <i>within an hour</i> of the initial attacks, i.e. United Flight 93).
