It depends entirely on the quality of the leaders behind the revolution. Compare the American Revolution to the Russian revolutions of 1905, 1917 and the period of 1918-1922. Everything was quite peachy after the former because they had a plan, they were intelligent and they were quite capable as leaders. Not so much with the latter, hence 4 (although I guess there were really only 3, because although the second revolution is split into two separate parts, they really are just halves of a whole) distinct revolutions in a very short time span, 2 of which happened during the same year.
As long as we're not just running out of our houses and burning everything to the ground, civil war is an unlikelihood over here. I'm sure there'd be a lot of arguments as to who should take over and so on, but I highly doubt we'd be willing to continue fighting over something that we can easily solve during breakfast.
That said, if our government decided to use the military against us, they could very well shut us down. Then again, I'm sure there would be a lot of high-ranking generals unwilling to attack the people they swore to protect, and would in the end help us continue fighting and eventually succeed.
