If the objective of a military campaign is to render military opposition ineffective, the US failed even militarily in Vietnam.

With respect, it has been obvious for several years now, at least, that the USA is the single greatest threat to the survival of life on earth (as we know it).

With the benefit of hindsight the increased role for Iran in the middle east is as obvious as the cane toad in Queensland, the grey squirrel in England, the rabbit in Australia and Japanese knotweed anywhere it is introduced. Eliminate the natural controls on a life form and it burgeons.

Now what are we going to do about human beings? Or is Iran (or the USA) going to do it for us?
