Fallon said that it was "illogical" for the UK not to bomb ISIL in Syria, for the organisation does not "differentiate between Syria and Iraq" and is "organised and directed and administered from Syria". Following the terrorist attacks on Paris in November 2015, for which Islamic State claimed responsibility, Cameron began pushing for a strategy for the Royal Air Force to bomb Syria in retaliation. Cameron set out his case for military intervention to Parliament on 26 November, telling MPs that it was the only way to guarantee Britain's safety and would be part of a "comprehensive" strategy to defeat IS. On 3 December 2015 MPs voted 397–223 in favour of launching air strikes against ISIL targets in Syria. The vote for military action was supported by all but seven members of the Parliamentary Conservative Party, as well as 66 Labour MPs who backed the government in defiance of their leader, Jeremy Corbyn, who had expressed his opposition to air strikes.
