U.S. Secretary of State Mike Pompeo defended on Saturday his nation's global role despite misgivings in Europe, vowing that Western values would prevail over Russian and Chinese desires for "empire."

Seeking to reassure Europeans troubled by U.S. President Donald Trump's "America first" rhetoric, his ambivalence over the NATO military alliance and tariffs on European goods, Pompeo said there was no crisis in Western leadership.

"I'm happy to report that the death of the transatlantic alliance is grossly exaggerated. The West is winning, and we're winning together," he said in a speech at the Munich Security Conference, listing U.S. steps to protect liberal democracies.
