When Clinton said removing Assad in Syria will be a No. 1 priority for her administration, she was playing to a certain constituency for votes. Obama has been saying the same thing since 2011.
Clinton also said the US “should pursue a diplomatic solution in resolving Syria’s internal conflict.” Who knows what that means, especially after the collapse of the recent cease fire in just days? It’s not as if diplomatic negotiations ever get much for the oppressed. The Oslo Accords surrendering Palestinian self-determination came out of one of those. Either that, or they’re a dog & pony show. But the substance is usually in the secret parts.
For antiwar activists, the US has no rights whatsoever to intervene in Syria, militarily or diplomatically. Nor do Russia, Iran, Israel, or all the other foreign forces.
