( CNN) The odd man out at the G7 gathering of the world's richest democracies, President Donald Trump cut a weary figure at a parting press conference Monday, where he boosted the pariah President vladimir putin, railed against Barack Obama, and once again boasted about the great relationship he and his wife, Melania, have with North Korean dictator Kim Jong Un.

In contrast, Emmanuel Macron emerged from the conference as an energetic leader who bypassed America to make a diplomatic outreach to Iran. The French President's deft conduct at the G7, which featured climate change as a main topic, was all the more notable because of Trump's clumsiness. As is his habit, Trump offered conflicting messages on the trade war he started with China, blamed his predecessors for the nation's troubles — and failed to note that Melania Trump has never gather Kim Jong Un.

Macron — and the world — are well aware of Trump's inability to work well with others. Indeed, at the last G7 Trump reneged on a commitment to affirm a pro-trade joint communique all the others wished to approve, and attacked the summit's host, Canadian Prime Minister Justin Trudeau, personally, calling him “very dishonest and weak.”
