The Establishment in the Labour Party has become entirely and dangerously detached from its activists. Hopefully, when their more purist notion of the membership returns Corbyn as leader once again, they will accept this as the verdict of the "long-serving members", acknowledge that their impressions and preconceived ideas have been wrong, and begin to unite behind the leadership against the government.
Leon Trotsky, not someone I usually quote, once said that people may not be interested in politics but politics is often interested in them. British people may be wary of foreign interventions but foreign crises can profoundly affect domestic politics. The suffering that we see every day in Syria won't go away and will have to be addressed, sooner rather than later.
