HRC repackages here "no-fly zone" as "safe areas." Robert Parry doesn't see it getting off the ground owing to US history regarding such agreement. The so-called safe areas would be areas from which to regroup, resupply and launch proxies to overthrow the Assad government, which the US has declared to be the overall policy objective.
HRC's "revision" is just a change in strategy.
Of course, when Syria and Russia reject it as such, the HRC will declare that she did "all she could" and the blame falls on them. US allies and vassals will fall in line, it is safely presumed.
