Doubt it, though I won't discount the possibility. The two things that I'd say are in the way are a lack of a uniting identity and democracy.
>identity
The Troubles had a clear cut between Catholic and Protestant, British and Irish, Republican and Unionist. America doesn't have that. You don't differentiate enough between them, your national identity is more free than ours. You could organise but you'd have trouble identifying an out group unless you follow racial lines, which Christianity (the strongest apsect of your national identity) would reject.
>democracy
The ultimate pressure release valve. People are more than willing to wait a few years for a possible decent candidate than they are to start a revolutionary cell. Mice will keep swimming when they think there's possibly a way out if they keep going. They'll swim until they die of exhaustion, the end result of our democracy.
The reason it's not impossible is because of retardation and chaos. The Troubles didn't begin with masks and Armalites, it began with riots that spiralled out of control. I think you're still far off from that but it's not impossible.
