“One must show that you won’t make small concessions, even symbolic ones, but also not over-publicize things, either,” said President Macron.
President Trump has a history of applying pressure when shaking people’s hands.
President Macron, perhaps mindful of this, wanted to show the American President that he was not a pushover.
