Like jakswan, I can't believe we're doing this again.
Well, Cameron has his own sexed up dossier - 70, 000 friendly fighters are just waiting the signal to start fighting IS. I just don't believe this - the US has spent a fortune training friendly rebels, who promptly decamp to IS, or just quit.
The peace plan looks very ropey. Russia is bombing rebel groups, and Hezbollah are mopping up afterwards, to help secure Assad. Is this what we're joining?
The Sunni tribes will go to IS, if they suspect that Iranian backed militias are advancing on them, as they did in Iraq. How is bombing going to stop that?
Meanwhile, the Saudis are bombing Yemen, and Turkey is bombing the Kurds - what a mad situation. Ah, but Dave 'call me Churchill' Cameron is on the way!
