Across two continents, across two days, world leaders gathered.
On Monday, in London, they joined Britons (and viewers worldwide) in affectionately remembering Queen Elizabeth II, whose historic 70-year reign spanned the twilight of the British Empire.
On Tuesday and for the rest of the week in New York, the sentiments weren't as affectionate for a modern-day imperialist, Russian President Vladimir Putin, whose illegal, immoral invasion of Ukraine became the focus of scores of speeches to the United Nations General Assembly.
Several implied that imperialism was in fact at the heart of Putin's heartless brutality.
"Let us speak plainly," President Joe Biden said. "A permanent member of the United Nations Security Council invaded its neighbor, attempted to erase a sovereign state off the map. Russia has shamelessly violated the core tenets of the United Nations Charter — [none] more important than the clear prohibition against taking territory of their neighbor by force."
Pivoting from his usual, useful geopolitical framework of an existential struggle between democracy and autocracy, Biden homed in on sovereignty, which even most autocrats automatically defend. "If nations can pursue their imperial ambitions without consequences," Biden said, "then we put at risk everything this institution stands for. Everything."
French President Emmanuel Macron reflected the theme of imperialism, too. And not just regarding Russia, but for fence-sitters, when he said: "Those who are keeping silent today are, in a way, complicit in the cause of a new imperialism."
The president representing the victims of this imperialism, Ukraine's Volodymyr Zelenskyy, told the delegates in rejecting Russian aggression that "the U.N. Charter proclaims the equality of nations, and we proved that Ukraine is equal among the equals."
