Since WWII, the US has been at war, and the government provokes China while using Russia as a scapegoat (Russiagate). As US hegemony declines, someone will fill the gap, and the US will put up a fight, but dropping nukes doesn't increase profits. However, an arms race will make plenty of weapon manufacturers richer.

Australia stupidly paid for ONE nuclear-powered submarine. On the bright side, nuclear energy is cleaner than diesel, and on the dark side, the US' theatrical show let the world know it's accepting orders for an arms race. Meanwhile, China's making trade deals in African and Latin American nations.

The US doesn't go to war over democracy, and it doesn't care about Taiwan, but US businesses could harness the fear of a nuclear war to replace the revenue loss from withdrawing from Afghanistan.

Unfortunately, nuclear war always looms over our heads because it's always a possibility, but the US media has been setting up the Russia-China tension for years. Oh, and the US military's UFO report claiming China or Russia must have developed advanced aircraft was weird, but who knows. Humanity blowing itself and the whole world up over its ego wouldn't be surprising. Ugh.
