As I stated. Now do you suppose there are those who might work and sacrifice to make that come true? A failing economy that was booming would be DJT's Achilles heel. Are there any in the world's ruling elite that could benefit from a Trump defeat in 2020?
I tend to doubt that they can pull it off; but I would be a fool to think they won't try. (To wit: the Fed's recent raising of the Fed exchange rate - called out by POTUS and the WH. And all the experts saying that a trade war with China will ruin our economy... The same folk selling the Brooklyn Bridge.)
No, I suppose not. Wouldn't be prudent. Europe and China and the rest of Asia are all in big trouble compared to us. If what you suspect is tried, they will all hurt much worse than us, and abdicate world economic leadership to us for a long time. It's not even mutual assured destruction.
Remember, when the USA gets a cold, the world gets pneumonia
