Hispanics and Mexicans would slauther every gringo and if your annexation attempt for Latin America and Canada happened to occur, Cuba and Venezuela would got Chinese and Russian nuclear missiles in the spot. Canada would just call the French for a good nuclear missile set. Either the USA steps back, or California gets turned into dust.
Texas would already had seceded and turned into a neutral state in order to avoid further issues. And OFC several states bordering Canada and Mexico would secede too joining Canada and Mexico themselves in order to fight Washington and Nevada. Because that's the way to avoid being a nuclear target. Similar stuff would happen in Russia too with states becoming independent so they aren't a target from both Europe and the USA.
China would just stare there thinking on the good chunk of money would get post war. It would just declare neutral too a la Switzerland asking for diplomatic agreements between the two sides.
The most probable war today with Russia would be an small one in the Arctic because of oil/gas, totally irrelevant and with few casualities.
