BRIDGETOWN, Barbados - ON SUNDAY, United States President Barack Obama was sworn in for his second term in office. He will have to shoulder the power and burden of the presidency in an increasingly turbulent world darkened by domestic discord and crises abroad. Obama has already said that he would root his second term in the crusade to build a more equitable economy which powered his triumph over Republican Mitt Romney but he is destined to face stiff resistance. Many analysts feel that Obama’s legacy will be determined by the way he handles the huge financial crises facing the United States which will impact on the economies of the rest of world which are reeling under the impact of the global crisis.
