@reasoning logic,
I don't disagree with that, RL. Obama/Clinton have gotten slammed for not pushing hard enough for the "no fly" thing, as have Britain, France, Germany et al.
The notion of some sort of unilateral intervention was never really an option. It had to go through the UN with China and Russia agreeing to abstain. That, alas, took time during which many people suffered.
I have no problem with Germany's decision. If you imagine this as a chessboard, the various countries are looking several plays ahead and are coming to different conclusions.
