Trump is still trying to make America great again. Biden has tried and the result is out there for all to see. Xi did not make such a proclamation but talked about the rejuvenation of the Chinese Civilisation and making life better for the Chinese people and the people of the world ... in a common future and shared destiny using a win win formula.
In the latest two session Congress in Beijing, the crux of the matter was China's economy and territorial integrity. American critics and bananas are only concerned about power consolidation by Xi as a double edged sword, implying something ominous going forward for China. None of them would talk about the future of America under a demented old man or a scoundrel whose integrity has been questioned in the American courts. Either of these two men becoming the President of America did not imply anything ominous, no double edged sword. Just a normal process of the great American democratic system, and the American Empire will continue to rule the world without a hitch.
In Xi there is a technocrat with a cool head steering China on its path towards rejuvenation through economic development, but always conscious of the threat posed by the evil Empire and the jesters in Washington, all out to contain and derail China's economic growth. For the latter, Xi is clear on what to do and the Chinese defensive capability is not neglected but persistently upgraded to meet the forces of aggression. China's defence industry is second to none, making progress in every field, churning out warships, warplanes and war machine like making buns.
Trump or Biden would have their hands full, also making a lot of weapons for the wars in Ukraine and the Middle East, and for more wars they are trying to start in East and South East Asia. And they will be spending all efforts and resources in sanctions and trade wars, all kinds of wars, instead of rebuilding a crumbling American infrastructure and economy with a 1% rock solid growth paired by 7% inflation. Their strategies are similar, put down others to make America great again. Throw all obstacles in the path of their enemies to trip them or to slow them down, and America would be great again, chucking along fine in its old ways. When all the competitors are cut down, no one would be able to stand up to make the Americans looked bad. America can live happily with ageing 4G, ICE motorcars, antique train network and fantasise about going to the moon 'again'.
Between Xi and Trump/Biden, who would be more successful in their missions to make their respective countries great or better? Who would be seen and respected as national leader and international statesman, and who would look like rogue and gangster chief?
Xi believes in Win-Win formula. I win, you also win.
Trump/Biden believes in America First. I win, you lose.
