Those who say Mr Cameron has been marginalised by the Parliamentary vote on Syria are quite wrong. Mr Cameron could play a crucial role. He should speak for peace. He should seek a way through the rows between the USA and Russia. He should speak out to get the participants in the crisis around a table.
He could also propose a different way of responding to Assad’s atrocities. Why not seek the agreement of the international community to outlaw Assad, telling him should he ever leave Syria he will have to stand trial for atrocities where there is evidence of his involvement, and taking further action to freeze any money and assets he and his cronies may have abroad until they have answered the charges against them. The very least the west should do is to proceed by legal means and establish the evidence.
