Could you see america become something similar to what the mongol empire was?

The United states as of today is the most powerful country on the planet compared to all other powers and nations combined. The mongols under temujin (ghengis khan) had destroyed the most powerful empire of the world in their day which was the persianized turkic kingdom of the khwarazmian empire and took its land and women and riches.

Imagine if someone today were to hack the system and somehow turn the us into a an absolute dictatorship and the military was on his side no matter what he did and did brutal invasions of Canada and Latin America and Africa and could easily fight off the world and sections. Couod you see a real life scenario of that happening?
