Visualizing the consequences of a nuclear war between the U.S. and Russia

That's about the way it's going to go.

Britain and France have nuclear capability and are obligated under NATO Article 5 to protect the United States, so Russia will strike them as well. The black ash and smoke lifted into the atmosphere will shut the planet off from solar heat for up to ten years. More than 5 billion people will die from explosions, radiation and starvation,... But!

I listened to an interview with a retired Russian general and he is convinced that nuclear war will happen with a 90% probability.
But he also thinks that a nuclear conflict between Russia and the United States will take place on the territory of third countries.
For example. The U.S. would launch a nuclear strike against the Russian military, for example in Poland. Russia will launch a nuclear strike on military bases, including US bases, in Europe (Britain, France, Germany...etc.)
And only then can there be a nuclear exchange between Russia and the USA.
