Equally troubling, the president sees no particular reason why he should explain to the American people why Washington's readiness to support Kiev's use of force against Russia makes strategic sense for America. 

In 1937, when the Imperial Japanese government expressed sincere regret for attacking and sinking the USS. Panay, an American gunboat that had been patrolling China's Yangtze River, US Ambassador to Japan Joseph Grew was not satisfied. He warned the Japanese Foreign Ministry that "Facts mean more than Statements."

Grew was right. A Biden-Harris guarantee of support for the Ukrainian government's plan to reconquer its lost territories, including Luhansk, Donetsk, or Crimea, is about as meaningless as the British government's 1939 guarantee of assistance to the Poles in the event of a German attack on Poland. 

In 1937, President Franklin D. Roosevelt decided not to retaliate against the Japanese. FDR knew there was no public support in the United States for a war with Japan or any other great power. FDR also resisted pressure from the US Navy's admirals to retaliate because he knew America's armed forces were not ready for a full-scale war. As for our British friends, they were not ready to weaken their fleet in the Atlantic to join a fight against Japan when the threat of war with Germany was growing.
