"There's nothing that difficult about building and deploying unmanned flying bombs, especially if you don't worry too much about precise targetting."

That is not a drone. That is called a "cruise missile." They have been around since WWII, called the V1. If it is so easy why has no non-government actor never deployed one?

It is hard for a terrorist to get their hand on high explosives. It is hard to get their hands on a remote controlled vehicle large enough to carry enough high explosives to do real damage.

It is so far, impossible for them to get their hands on a non-line of site control device that is secure from jamming or detection with enough bandwidth for a video signal to be transmitted back to the operator to allow for the piloting of the vehicle. Certainly not. not by a long shot. Is that day coming? Maybe. Probably. But it is not here now. It is far from easy.

As far as "Al Qaeda" franchises using it in America. Suicide Vests and trucks full of fertilizer are far cheaper and easier. And Al Qaeda has yet. (knock on wood) to pull off even one of those attacks in America. But already they are graduating into science fiction.

It was a dumb thing to say. Just like the rest of the alarmist superstitious unwarranted associations on this thread.
