“A majority of Americans believe the US plays a less important and powerful role in the world than it did 10 years ago, according to a long-running study that found that most people now believe America should ‘mind its own business internationally’. It is the first time the survey of US foreign policy attitudes has recorded such a sentiment in almost four decades of polling. The findings, published on Tuesday by the Pew Research Center in association with the Council on Foreign Relations, suggest Americans want their leaders to adopt a less interventionist approach, although there is a growing desire for the development of stronger trade and business links abroad.”
