Patrick Cockburn, who has for many years been employed as Middle East correspondent for the Financial Times and now The Independent and who has won many prizes for his journalism and books on the Middle East, wrote an article in The I today.
In it he states:
"..... Yet the Defence Secretary, Michael Fallon, was this week claiming that our allies on the grounds are going to be 'moderate opposition forces in Syria who have been fighting the regime in Syria and resisting ISIS.
"He did not identify these elusive moderates, but the Syrian armed opposition is dominated by three extreme Islamic fundamentalist groups, of which the most powerful is ISIS, followed by the al-Qaeda affiliate Jabhat al-Nusra and Ahrar al-Sham, a hard-line Sunni movement."
That seems to support what the Russians are saying - that the vast majority of anti-Assad fighters belong to groups broadly in sympathy with the aims of ISIS.
I don't think it's a good idea for Russia or anyone else to be dropping bombs on Syrian towns and cities because it is too easy for mistakes or bad decisions to be made - as we have seen with the bombing of the Medicine sans Frontiers hospital in Afghanistan. And anyway I find it difficult to believe that such bombing can take place without civilians being hurt or killed - and further enemies being made.
As more people are starting to say, what should be stopped is the flow of money, oil and weapons between ISIS and whichever countries are either buying their oil or supplying them with weapons and armoured vehicles. There have been some reports that Russia has attacked ISIL-held oil installations and if it's true that seems to me to be a more effective way of shutting them down.
