The tring that Ukraine and Arab Spring have in common - is that same folks that managed to bring Milošević down in Serbia (known as Resistance/Otpor), later went on to talk/teach protestors in Ukraine, Egypt ...etc.

Check out #Post Milošević; and #Legacy; sections on https://en.wikipedia.org/wiki/Otpor (couldn't figure out how to get deeplinks on mobile).

TL;DR: Besides Ukraine and Egypt, they went to a few more places, in some it worked, in others it didn't. And there were revelations of foreign (e.g. USAID) funding.
