Its worked too. Look why happen in the UK when Cameron tried to get support for an intervention.
It hasn't worked. For a start, the lack of UK support for intervention in Syria was multi-faceted and had much more to do with an anti-war sentiment amongst the public following the mishaps of the Iraq war. Also to do with the perceived financial cost when the UK government was on an austerity drive and cutting back on public services. Even then, it was a close vote (285 to 272).
Even after the recent attacks in Paris, the French have vowed a “merciless” response.
If anything, attacks on western countries and interests are emboldening us to get more involved. The attacks are softening the anti-war arguments.
