I think the US desperately wants one, and I think the powers that be are going to desperately try to start one, but I don't think they'll get one. The cold war was able to happen because of strong social cohesion among everyday Americans who had participated in WWII allowing the government at the time to do as they pleased and pass draconian and corrupt policies (even for the times) that normally wouldn't be forgiven. They still almost had civil war among veteran groups despite the somewhat prosperous times (America was still on the gold standard until the 70s).
I don't know if the feds believe that they can recreate the economic prosperity and control of the cold war or if they are just falling for the "war equals good for the economy" meme, nevermind the fact that if you look at the economic losses of each soldier killed, war is shit for the economy long-term,
but the country is divided, veterans are fed up, nd people who do join the military are closer to glorified mercenaries than to soldiers, working for benefits or to fast track an apprenticeship when they get out (the military hasn't helped by kicking everyone out after 15+ years of service to avoid them hitting the 20 year retirement-for-life clause).
tl;dr- Trying to reenact the Cold War in America is likely to result in either economic collapse or civil unrest at levels that make the current riots look like child's play.
