I'd like to point out that, assuming that the terrorist attacks in London were perpetrated by Al-Quaeda / Muslim "extremists" - Der Spiegel and BBC Monitoring have reported a claim of responsibility by "Secret Organization - AlQuaeda in Europe" as an act of retribution for UK involvement in Afghanistan and Iraq - having various western "leaders" condem the attacks as barbaric and inhuman is pretty poor sportsmanship, if not outright "whiny little spoiled baby-ish".
What do you think the majority of civilian Afghan and Irqi casualties and their surviving relatives think of what the UK did to them? That's right, barbaric and inhuman. Which it is. Both situations are. Once you accept THAT, then you start frantically trying to stop it.
"You're killing me, stop!!"
"NO! You're killing ME! YOU stop!"
"NO, YOU!"
My sympathies to all involved and affected. All of this is going to get much much worse before it gets any better, and it won't be in any of our lifetimes. :(
