If the pressure for a punitive US strike is taken off, there's room for either:
1) A negotiated settlement that is palatable to the big kids on the sidelines (Russia and the US, primarily) or
2) A continued stalemate.
The latter scenario is not great for the Syrian people, but since there does not seem to be any great appetite for "regime change" intervention among US leaders or people (myself included), it at least lessens the possibility of a wider conflict.
Obviously, there's no sense in counting chickens here, but it's a relief to see some daylight. And, in light of some of the political grenades that have been lobbed, it's also worth noting that Obama's language (there is no military solution to the conflict) is consistent with that of the other big non-belligerent player (Russia). For all of the crap that Obama has taken, he's been willing to sweat during peace to avoid our bleeding during war.
We can disagree about what—if any—action should have been taken when, but can we at least agree that perhaps we're not engaged in a grand conspiracy to fake a chemical weapon attack to take out the Assad regime, and that perhaps Obama's foreign policy team hasn't been abducted by rabid neocons?
