I have closely watched American presidencies since Richard Nixon in early 1970s, and none has been as hectic and eventful as Donald Trump presidency. Over the last four years, Mr Trump has surely upset global status quo through his impromptu and often unplanned policies and pronouncements, all coming in quick successions. Since USA is perceived as the leading global power, the world closely watches and analyses whatever USA does, because its actions have direct and indirect impacts on the rest of the world.
Global order as we have known it for many years has been shaken by Mr Trump into situations of uncertainty and sometimes "chaos" especially in areas of global protocols, geopolitics, trade, and political governance standards. Arrangements and institutions that have previously sustained global order and prosperity have been upset.
