Trump turns the G-7 into the G-6 vs. G-1

February 2016, I warned in an article co-written with economist Benn Steil that “a Trump presidency threatens the post-World War II liberal international order that American presidents of both parties have so laboriously built up — an order based on free trade and alliances with other democracies. His policies would not make America ‘great.’ Just the opposite. A Trump presidency would represent the death knell of America as a great power.”

.. In just the past few weeks, he has taken a giant step toward destroying the global system that the United States created after 1945.

.. Trump has now exited three major treaties — the Trans-Pacific Partnership, the Paris climate accord and the Iran nuclear accord — and thrown into doubt the future of another — the North American Free Trade Agreement — while launching a reckless trade war against our closest allies.

.. Trump continued to push his irrational idée fixe that the United States — the richest nation in the world — has been victimized by its friends.

.. Trump looks like a defendant who has just been found guilty by a jury of his peers.

.. Justin Trudeau did not mince words, calling the U.S. tariffs “insulting” and saying: “Canadians, we’re polite, we’re reasonable, but we also will not be pushed around.”

.. Larry Kudlow accusing Trudeau of a “betrayal” and Peter Navarro saying there’s a “special place in hell” for the Canadian prime minister.

.. No U.S. officials have ever spoken this way about any U.S. ally, ever. These are the kind of words that normally precede military action.

.. Trump seems amazed to discover that the European Union (gross domestic product: $17.1 trillion), Japan ($4.8 trillion), and Canada ($1.6 trillion) — which together produce more than the United States ($19.3 trillion) — will not be pushed around as easily as the contractors he has gotten used to stiffing.

.. add Russia. This was a bizarre suggestion, given that Russia is not only an international outlaw but also an economic pygmy whose GDP does not even rank in the top 10.

.. If the G-7 were to expand, it should include India and Brazil, both democracies that have larger economiesthan Russia’s.

.. invasion of Ukraine — an act of aggression for which Trump perversely blames President Barack Obama — and it has done nothing since 2014 to deserve readmittance. Instead, its meddling in U.S. elections its and war crimes in Syria demand more punishment.

.. Trump is doing precisely what Putin hoped would happen when he helped Trump get elected.

..  A new poll finds that only 14 percent of Germans consider the United States a reliable partner, compared with 36 percent for Russia and 43 percent for China. That the citizens of one of America’s staunchest and most important allies now look more favorably upon our illiberal foes is a testament to Trump’s unrivaled wrecking abilities.

.. none of those disputes called into question the fundamental unity of the West in the way that Trump’s stupid and self-destructive actions do. The Atlantic alliance was born in Canada in 1941 and may well have died there in 2018.
