While all facts are true, not all facts are relevant.
And what are the relevant facts in this crisis where 100,000 Russian troops are now stationed along the Ukrainian border?
Fact one: There is not now and never has been a vital U.S. interest in Ukraine to justify risking a war with Russia.
History tells us that. Even as Ukraine was suffering in the Stalin-induced Holodomor, the terror-famine of 1932-33, President Franklin Roosevelt granted diplomatic recognition to the Bolshevik regime.
During four decades of Cold War, the U.S. never regarded Moscow's control of Ukraine as any threat to the USA.
President Joe Biden was thus right to rule out military action in response to any Russian incursion or invasion of Ukraine.
Moreover, as it is declared U.S. policy not to retaliate militarily to an invasion of Ukraine, Biden should make it clear that Ukrainian membership in NATO is a closed question.
Not going to happen.
Ukraine is not going to be invited to join NATO and be given Article 5 U.S. war guarantees that are the primary benefit of membership.
