What enemy? There is no enemy out there that presents an actual credible threat to the existence of the USA or to our North American way of life. No one out there has the military capability to present a credible threat to the USA, with the possible exceptions of Russia and China...and what motivation would they have to do so, since the USA is capable of devastating them both with a nuclear counterattack?

The foreign countries that the USA has been militarily involving itself in recently (Afghanistan, Iraq, Lybia) and has threatened to involve itself in (Iran, North Korea, Pakistan) are small powers who present no credible threat to the survival of the USA. None. They are absolutely incapable of presenting such a threat. They were never capable of presenting such a threat. To imagine they have "aggressive plans" against the USA is like imagining that a mouse is planning to take down a cat, for heaven's sake.

Nor was Vietnam ever capable of presenting such a threat, nor did they have any intention of doing so...they were simply achieving their national sovereignty and ending a colonial occupation. Empires have long justified their invasions and occupations of small countries on a supposed threat of some kind posed by those small countries. Hitler had most Germans convinced in 1939 that Poland was a threat to Germany, and was viciously persecuting German nationals on Polish territory. Utter nonsense, but most Germans, of course, believed it...at the time...because that's what their media told them to believe.

Likewise, Americans who think Iran or Iraq or Afghanistan or North Korea or Lybia present any kind of actual, credible threat to the survival of the USA or the survival of our way of life are subscribing to utter, arrant nonsense.

But...it's typical propaganda. Standard stuff. So I'm not surprised it is being used to sway people's minds.

Empires CAN'T tell their public the real reasons they go to war. People wouldn't like it, and they wouldn't support the war effort. It would result in a public who utterly lost faith in their government, and that's the last thing any government wants to have to deal with....so they lie to you about why they're going to war. They make it sound noble, and they make it sound like it's self-defence. It isn't. Specially when the country you go to war with is the size of a mouse, and you're the size of a lion.

No foreign country planned 911. 911 was planned by a group of conspirators. I won't bother suggesting who they were, because there's no way I can know that for certain, but they were not representing any sovereign nation, and certainly not Iraq or Afghanistan...they were representing their own private interests. What those interests may have been is an interesting question, and there are a number of possible answers. Whatever the answers, to respond to that attack by invading any other sovereign nation was an idiotic thing to do....but I suspect it was exactly what the conspirators wanted to see happen in the wake of such an attack. And they got their wish, didn't they? And you see the disastrous results.

On the day Russia or China decide to fight a great war with the USA, mg, then you will have a real enemy. At present, there is no such real enemy....but an empire always needs some fictional enemies if it can't find real ones. What else would keep the great paranoid military-industrial game rolling?
