Chief executives of Indian information technology (IT) and pharmaceutical companies won’t be the only ones scrambling to reorient their strategies after US President Donald Trump’s inauguration speech that dissed the four former presidents with whom he shared the podium and painted a grossly inaccurate picture of America. From China to Europe, the implications of “America First” and the declaration that “protectionism will lead to greater prosperity and strength” – two key takeaways from the former realtor and reality TV star’s opening address – have sent out the unmistakable message that the world’s only superpower and largest consumer market would be reverting to the kind of isolationism last seen in America in the 1930s. In stating these views, Mr Trump may have belied the hopes of those who thought that accession to office would temper the more extreme proclivities of his crudely divisive campaign, but the campaign speech had a virtue of sorts in its blunt reiteration of intent. That the only certainty going forward is uncertainty was underlined by the cautious movements in the financial markets in the weaker dollar and falling yields on US treasuries.
