LAUGHINGSTOCK:

The newly elected French president, Emmanuel Macron, went first. It makes sense that the Frenchman would defend the international treaty that bears the name of France's capital: The Paris Agreement. "Climate change is real and it affects the poorest countries," Macron said.

Then, Canadian Prime Minister Justin Trudeau reminded the U.S. president how successful the fight against the ozone hole had been and how it had been possible to convince industry leaders to reduce emissions of the harmful gas.

Finally, it was Merkel's turn. Renewable energies, said the chancellor, present significant economic opportunities. "If the world's largest economic power were to pull out, the field would be left to the Chinese," she warned. Xi Jinping is clever, she added, and would take advantage of the vacuum it created. Even the Saudis were preparing for the post-oil era, she continued, and saving energy is also a worthwhile goal for the economy for many other reasons, not just because of climate change. [...]

Still, it is likely that none of the G-7 heads of state and government expected the primitive brutality Trump would stoop to when announcing his withdrawal from the international community. Surrounded by sycophants in the Rose Garden at the White House, he didn't just proclaim his withdrawal from the climate agreement, he sowed the seeds of international conflict. His speech was a break from centuries of Enlightenment and rationality. The president presented his political statement as a nationalist manifesto of the most imbecilic variety. It couldn't have been any worse.

His speech was packed with make-believe numbers from controversial or disproven studies. It was hypocritical and dishonest. In Trump's mind, the climate agreement is an instrument allowing other countries to enrich themselves at the expense of the United States. "I was elected to represent the citizens of Pittsburgh, not Paris," he said. Trump left no doubt that the well-being of the American economy is the only value he understands. It's no wonder that the other countries applauded when Washington signed the Paris Agreement, he said. "We don't want other leaders and other countries laughing at us anymore. And they won't be. They won't be." [...]

The U.S. is led by a president who feels more comfortable taking part in a Saudi Arabian sword dance than he does among his NATO allies. And the estrangement has accelerated in recent days. First came his blustering at the NATO summit in Brussels, then the disagreement over the climate deal in Sicily followed by Merkel's speech in Bavaria, in which she called into question America's reliability as a partner for Europe. A short time later, Trump took to Twitter to declare a trade war -- and now, he has withdrawn the United States from international efforts to combat climate change. [...]

For Merkel, who grew up in communist East Germany, the alliance with the U.S. was always more than political calculation, it reflected her deepest political convictions. Now, she has -- to a certain extent, at least -- terminated the trans-Atlantic friendship with Trump's America.

In doing so, the German chancellor has become Trump's adversary on the international stage. And Merkel has accepted the challenge when it comes to trade policy and the quarrel over NATO finances. Now, she has done so as well on an issue that is near and dear to her heart: combating climate change.

Merkel's aim is that of creating an alliance against Trump. If she can't convince the U.S. president, her approach will be that of trying to isolate him. In Taormina, it was six countries against one. Should Trump not reverse course, she is hoping that the G-20 in Hamburg in July will end 19:1. Whether she will be successful is unclear.

Trump has identified Germany as his primary adversary. Since his inauguration in January, he has criticized no country -- with the exception of North Korea and Iran -- as vehemently as he has Germany. The country is "bad, very bad," he said in Brussels last week. Behind closed doors at the NATO summit, Trump went after Germany, saying there were large and prosperous countries that were not living up to their alliance obligations.

And he wants to break Germany's economic power. The trade deficit with Germany, he recently tweeted, is "very bad for U.S. This will change."

Merkel's verdict following Trump's visit to Europe could hardly be worse. There has never been an open break with America since the end of World War II; the alienation between Germany and the U.S. has never been so large as it is today. When Merkel's predecessor, Chancellor Gerhard Schröder, refused to provide German backing for George W. Bush's invasion of Iraq, his rebuff was limited to just one single issue. It was an extreme test of the trans-Atlantic relationship, to be sure, but in contrast to today, it was not a quarrel that called into question commonly held values like free trade, minority rights, press freedoms, the rule of law -- and climate policies.
