The west would like to forget Syria but it refuses to be forgotten. Since the civil war there began in 2011, our expressions of sympathy with its benighted people have followed an oddly cyclical, almost ritualistic pattern. Every summer, when our politicians are away on holiday, news from Syria seems to have an odd way of flooding back into the headlines. Something gruesome unfolds that once again draws our attention. There is a tragedy to prick our conscience, or some new horror – perpetrated by the regime or its enemies – to shock our sensibilities.
The crisis in Syria is developing fast. Iranian and Russian involvement is increasing by the week, in addition to the role played by Saudi Arabia and the other Gulf states in funnelling money into the conflict. US policy is likely to develop considerably over the next few months, as it is widely agreed that the existing approach has not achieved its aims. France has announced a new aerial campaign against Islamic State. The real choice facing Britain will be whether it, too, is capable of, or willing to, play a part.
