That's why I don't trust any source posted by "anonymous".

It honestly wouldn't be in any country's best interest to start a nuclear war or try to destabilize the U.S economy in any way. The U.S dollar is the most circulated fiat currency currently available. Losing the U.S economy would hurt almost every major first world country out there significantly because these countries do a lot of trading and business in dollars. A nuclear war would be even worse because it would be a threat to most human lives on the planet. Without humans, we wouldn't have an economy.

So yeah, since money runs the world, I don't see such a decision being made that would actually be a threat to the goals and interests of those who actually run the world. Even in the very unlikely event that Russia would actually try to start something with the U.S, I doubt that they could do something as significant as "destabilize our economy" because we have the most powerful military force out of any country in the world and some of the most advanced technology.

I see nothing to worry about here.
