Prime Minister David Cameron is looking to do more in Syria against ISIS. Today his Minister of Defence, Michael Fallon, made the case before Parliament that the UK should participate in coalition airstrikes against ISIS inside Syria. The UK government’s renewed interest in undertaking airstrikes in Syria is driven largely by the attack last week on tourists in Tunisia, in which 29 or 30 of the 38 killed were Brits. (Officials are investigating links between the attacker and ISIS.) Cameron’s government also seems motivated by the idea that limiting uses of force to Iraqi soil makes little strategic sense when ISIS itself treats the Iraqi/Syria border as irrelevant.
