U.S. President Barack Obama said on Friday that Donald Trump's recent comments that South Korea and Japan should acquire nuclear weapons show the leading Republican presidential candidate is not well informed on international relations.


"What the statements you mentioned tell us, they tell us that the person who made the statements doesn't know much about foreign policy or nuclear policy or the Korean peninsula, or the world generally," Obama told a news conference at the conclusion of a nuclear security summit.
