So Dick Cheney may or may not have written a book that may or may not be a tutorial as to how to lure young homeless people into your house so that you may harvest their organs for later use. This means we get to hear him defend his life's work, aka the Iraq War, and you will not be surprised to know that he considers it a fine success because we were able to find out that there weren't any weapons of mass destruction there.
What we gain and my concern was then and it remains today is that the biggest threat we face is the possibility of terrorist groups like al Qaeda equipped with weapons of mass destruction, with nukes, bugs or gas. That was the threat after 9/11 and when we took down Saddam Hussein we eliminated Iraq as a potential source of that.Whether Iraq actually had any weapons of mass destruction, you see, is beside the point. The point is that by invading them, unleashing a chaotic series of events that killed perhaps a half a million people or so, we were able to set our minds at ease as to how they did not have any. Scratch one country off the list; all that is required now is to bomb and invade every other nation in the world so as to satisfy ourselves that there are not any illicit weapons there either. You may recognize this as another rephrasing of the Cheney Doctrine, which says that if there is even a one percent chance that another country might do something bad to us, we are allowed to bomb and invade them before they get the chance. If bombing and invading them did not result in them liking us sufficiently, of course, we may have to bomb and invade them again; there is no common rule of thumb as to how many times you need to bomb and invade someone before they like you.
Dick Cheney was and is considered an American foreign policy expert. He was one of the people most intimately involved with deciding who should and should not be killed because reasons. All of the others are still around as well, flitting about on their occasional legally mandated Famous Person Book Tours. There is at least a 99 percent chance that they are all secretly idiots or worse, but the law is the law.
