French President Emmanuel Macron is defending his push for more robust European defense in a meeting with President Donald Trump.

As the two men met at the French presidential palace Saturday, Macron called Trump “my good friend” and even appeared to tap him on the thigh. The two men have had an up-and-down relationship.

Their meeting got off to a tense start after Trump called it “insulting” that Macron wants a European army. Macron defended the idea, saying “It’s unfair to have European security today being assured by the U.S.”

“That’s why I believe we need more European capacities and more defense to take this part of the burden,” he said. He says the states in the U.S. don’t ask France or Germany or other countries to finance their armies.
