It would be nice for a bit of international support in this effort other than rhetoric.
Come you Brits! grow some bollocks.
The US needs to save face on this one by not appearing to be the only ignorant hawkish brutish country willing to kill in the name of non violence.
They're not alone. Germany has come out in full-throated support of military action. Not that Germany will do anything about it of course, but they've promised that if the US invades, the German government will be cheering - from a long distance away.
Francois Hollande is also in favour of military action, and is willing to get his hands dirty. Constitutionally, the French President does have the power to go to war without asking the parliament, but he's under huge pressure to out this to parliamentary vote anyway. Given that a lot of his own party, along with about 2/3 of the French public, are opposed to military action, he'd probably have no more success than the British government did in getting a vote in favour of intervention. Intervening anyway would probably destroy the little public support he has left, but then my left arse-cheek has more chance of winning the next Presidential election than Hollande does, so maybe he's past caring at this point.
