My question, Since it is your premise to make America great again, ‘when was American great?’
While we, with our myopic vision, tend to see cycles, in reality history (time) is currently plotted in linear schemes, which allows for the potential continual and gradual growth (absence worm holes).
The irony here is that there is no true Nationalism. Nationalism in North America belongs to the Indigenious Peoples (Native America Indians); all others are European, Asian & African immigrants or invaders. The same is true in all nations of Europe if you go back in history. Selective history is not History.
