It's hard to imagine because that's not what they want. Of course you'll see the comparisons of Japan and Germany from those to refuse to accept reality but it doesn't change the facts. You've made the point quite clearly. These are nothing more than nation states established by British map makers.
The only concern I have in the region is Israel. And there I believe in full 100 percent protection of said state. However this protection does not include an offensive action on every Arabic state in the region.
The West may very well not have the ability to stop the rise of the Islamic superstate. By trying to establish a democracy in the region (the right to choose one's own form of government) it possibly could have laid the groundwork for an even quicker establishment of such a state. And considering long term relations, it very well may not want to stop it. It could even bring stabilization to the region.
I think we are in general agreement, accept that I don't think the West (usa/uk) has any choice but to try to seed secular democratic government in Iraq, most likely the winds of muslin nationalism will sweep us out of the area but maybe just maybe we (west) and the Iraqis will succeed. Certainly worth a try as the price for failure will be very very high.
