Immediately the "peace keeping" troops left Iran, sectarian war broke out. Clearly this was totally unexpected by our western politicians, but to anyone who is familiar with the history of the area, it was entirely predictable. There has never ever been peace in the Arab world except where there was a strong man in control, and for all that has been said about Saddam, far more Iraqi lives appear to have been lost since he was deposed than during his tyrannical rule. Indeed the only peaceful area of Iraq is that inhabited by the Kurds, who would like to form their own independent country, but have been prevented from doing so by the West, largely at the behest of Turkey.
So moving on to Afghanistan, is there anyone who doesn't believe that exactly the same will happen there the day after the troops pull out? Why do we continue to allow our soldiers to be killed for a clearly unrealisable goal? Surely there can't be any of our politicians who are stupid enough to believe that Afghanistan will settle down to be a peaceful country with democratic rule?
I see exactly the same problem in Egypt and Libya The so called Arab Spring in Egypt is turning to a winter of discontent, and no doubt Libya is following not far behind.
The fact is that democracy in all these countries is still stuck in the 12th century in British terms, but unfortunately they have 21st century weapons at their disposal.
