As President Donald Trump follows through on his promise to be “America First,” he appeared to acknowledge the interconnectedness and mutual dependency of the global economy during his address to the World Economic Forum in Davos, Switzerland.

“The USA is the economic engine on the planet,” Trump told the crowd Wednesday. “And when America booms, the entire world booms. It’s been the history. When it goes bad, it goes bad. You all follow us down, and you follow us up.”
