The debate in the House of Commons was thorough, and the horror and revulsion at recent atrocities in Syria, Paris, Beirut and elsewhere is shared by MPs from across the political divide. Yet I have still to see any evidence to suggest that UK bombing Isis targets in Syria is likely to increase our security here in Britain or help bring about a lasting peace in the region in question - to the contrary, the evidence appears to suggest it would make matters worse.
We all wish to see an end to the war in Syria and end to terrorist attacks. We all want peace to be achieved in the Middle East and in the wider world. The decision facing our Parliament is whether UK military action in Syria now can deliver that. I believe that the Prime Minister has not demonstrated that sufficient lessons have been learned from UK military action in Afghanistan, Iraq and Libya.
The 2003 vote to invade Iraq has haunted Labour ever since - losing millions of votes that have yet to be regained and causing around half the party's membership to resign. Nothing in Labour's history has traumatised it quite so much perhaps. Now again Labour is being asked to support a war that lacks clear United Nations sanction - or a coherent purpose.
In the interests of taste and decency, let us look away from the gruesome spectacle of the civil war that has engulfed the Labour party and concentrate instead on the far more serious conflict in Syria. So here are some questions that you might like to ask yourself (with my answers) before you decide whether you agree with David Cameron that the UK should now join the international military action against IS in Syria.
