Trump Renews Attacks on NATO and Trade Imbalances

WASHINGTON — President Trump, fresh off an international display of unity among global leaders to mark the end of World War I, renewed his attacks on America’s longtime allies on Monday, and demanded fair treatment for the United States.

In a trio of Twitter posts, Mr. Trump said that the United States pays “for LARGE portions” of other countries’ military protection and loses money on trade with the same countries. Mr. Trump has frequently criticized what he asserts are the unbalanced costs of the North Atlantic Treaty Organization, the military alliance whose core includes mutual defense.
