Whether for or against proposed military action targeting Islamic State (IS) in Iraq, it is more than a little hypocritical for the Labour Party to attack the SNP for voting against the motion to launch air strikes.
Some 23 Labour MPs also voted against the motion, including five Scottish MPs. Another 14 Labour MPs did not even bother to turn up to vote.
There are few opposed to taking military action on principle, especially when dealing with a reign of terror orchestrated by IS which has seen beheadings, including those of British citizens, rapes and crucifixions.
However, there seems little idea about how the success of the campaign is to be measured, especially when there is limited ground support from the Iraqi army – and there is no commitment to post-conflict resolution.
Mr Cameron has stated that military action must be part of a “comprehensive” political and humanitarian plan. What that is has not yet been made clear, and more detail is required about how the campaign is envisaged to develop, with a clear timescale and identified aims.
