Trump outlines foreign policy positions

Republican presidential front-runner Donald Trump confronted doubts on Monday about the depth of his knowledge of world affairs, delivering a sober speech to a pro-Israel crowd and outlining for the first time his team of foreign policy advisers.

In a lengthy interview with the editorial board of The Washington Post, Trump outlined a distinctly noninterventionist approach for the United States in the world.

"I do think it's a different world today, and I don't think we should be nation-building anymore," Trump said. He stressed instead the need to invest in infrastructure at home.
