The U.S. does not have a vital interest in igniting World War III over Ukraine. From Patrick J. Buchanan at buchanan.org:
Speaking to Congress, Ukrainian President Volodymyr Zelenskyy asked for many things from the United States.
He wants us to establish a no-fly zone over Ukraine. He wants the Soviet-era MiGs that NATO allies (from their Warsaw Pact days) have in their arsenals. He wants Russian-made S-300 antiaircraft systems in NATO inventories transferred to Kyiv.
He wants the U.S. to sanction every Russian official who does not repudiate this war on Ukraine. He wants all U.S. companies to pull out of Russia. He wants all Russian-made goods kept out of U.S. markets.
In short, Zelenskyy wants the U.S. as a full-fledged ally in Ukraine’s war against the Russian invaders.
But while America also seeks a defeat for Russia’s aggression, President Joe Biden has a higher imperative: to avoid a war between the United States and the world’s other nuclear superpower, Vladimir Putin’s Russia.
On Jan. 20, 2021, Joe Biden took an oath:
“I do solemnly swear that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States.”
And when the issue arose as to whether he, as president and commander in chief, would transfer MiG-29s to Ukrainians fighting Russians for their independence and freedom, Biden said no.
