This January sees the inauguration of Donald Trump as President of the United States for the second time. Although it should be an occasion for Americans to unite under a new presidency, the truth is likely to be bleaker. The US was profoundly divided by the election and is unlikely to be any more unified under President Trump, at least in the short term. It would be pleasant if the inauguration sees him seeking to bring the nation together and to heal some of its divisions. Nonetheless, many Americans will feel a renewed sense of optimism at this fresh start.
