So long as the Left doesn't get it's way here, the US will remain the top super power. If you look at the US, it's a lot like the Roman Empire. The way it's established right now, no foreign power can bring it down: economically (except for MAYBE China, but even that's doubtful), military, opportunity, and legislatively. That's how the Roman Empire was. The only real way to make this country crumble is from within. Usually it happens by targeting its wallet by means of entitlement programs, government ran institutions, and new regulations. Look at Medicare For All ($30 trillion) and the Green New Deal ($90 trillion). Those two bills alone would wreck this country. $120 trillion is nothing to sneeze at. No country in the world has that kind of money. Even combining all the rich people in the world today can't match that. You would have to exhaust other countries' resources to get that amount. That doesn't even include our $20+ trillion national debt. So the only thing that would bring down the US is Leftist policy, not Right wing nor moderate policy. For now, thank God the Democrat field of Presidential candidates is filled idiotic, delusional people that accomplished NOTHING. At least nothing that they could ever hope to achieve like what Trump had. As long as we have someone in the White House, Congress, and SCOTUS, who ISN'T a Leftist, the US will remain the world's number 1 super power.
