so, p'raps it did not "achieve" anything, but p'raps this is the incorrect question. It became resonant in the West, so it was validated in success and failure on this meta level, completely divorced from facts on the political ground. It may have highlighted the American doctrine of freedom and democracy, are not a linear progression and can be developed with a whitepaper from the state department or pentagon. perhaps freedom and democracy, is not the ultimate priority for some under repression from the state, the priority is merely to revoke the yoke of oppression...
Yeah, I think 'success' means different things in the eyes of individual beholders, for sure. As does 'repression'. For me, I was thinking along the lines of what the ordinary man or woman on the ground gets out of it. In Egypt we saw the Muslim Brotherhood briefly come to power before the military rolled in with more undemocratic dictatorship that the U.S is silent about.
In Bahrain we saw people pissed off in the streets before being crushed by troops from a neighbouring country, restoring the undemocratic nature of that nation. Which the U.S was also silent about.
Yemen - I'm still trying to work it out.
