Will the USA be plunged by political extremists from the right and left into a second civil war.

Hi everyone , those that have been paying attention to the news will notice that recently a vicious cycle has been taking place, with both sides of the far end of the political spectrum provoking each other to more and more extreme rhetoric and actions. My question is do you think the vicious cycle will continue into civil war, or will something stop the escalation. If you think something will break the cycle please describe it. (Everyone converting suddenly to your ideology dosn't count.)
