On the surface, Donald Trump was on his best behavior: flattering fellow leaders in Biarritz at the Group of Seven summit, tweeting his delight at being there, and even somehow resisting the urge to tweet about a shock visit to this seaside city by Iran's foreign minister.
The smiles were wide, the handshakes warm. "Everybody's getting along!" Trump said, minutes after he arrived.
But beneath the surface, Trump was still Trump — just as hard-line as ever, just as resistant to compromise, and just as sure he's right as the allies are sure he's wrong.
