“Probe with bayonets”

“Probe with bayonets. If you encounter steel, withdraw. If you encounter mush, continue” is credited to Soviet leader Vladimir Lenin (1870-1924). THe book The Unknown Lenin:
From the Secret Archive
(1996) includes this from September 1920:
 
”[W]e said among ourselves that we must probe with bayonets whether the social revolution of the proletariat in Poland had ripened.”
 
Political newspaper columnist Joseph Alsop wrote in 1975, “They (Soviets—ed.) merely follow Lenin’s advice to probe with bayonets any situation that looks mushy, withdrawing only when the bayonets meet steel.” The Lenin saying has been cited by American political figures such as Richard Nixon (1913-1994) and Grover Norquist.

Vladimir Ilyich Ulyanov (Russian: Влади́мир Ильи́ч Улья́нов; IPA: [vlɐˈdʲimʲɪr ɪˈlʲitɕ ʊˈlʲanəf], alias Lenin (/ˈlɛnɪn/; Russian: Ле́нин; IPA: [ˈlʲenʲɪn]) (22 April [O.S. 10 April] 1870 – 21 January 1924) was a Russian communist revolutionary, politician and political theorist. He served as head of government of the Russian Soviet Federative Socialist Republic from 1917, and of the Soviet Union from 1922 until his death. Under his administration, the Russian Empire was dissolved and replaced by the Soviet Union, a one-party socialist state; all land, natural resources, and industry were confiscated and nationalized. Ideologically a Marxist, his political theories are known as Leninism.

The Soviets have no grand, Hitlerian plan of conquest. They do not take Hitlerian risks. They merely follow Lenin’s advice to probe with bayonets any situation that looks mushy, withdrawing only when the bayonets meet steel.

Yet Democrats and honorable Republicans should have had the courage to say that this definition was unacceptable. Instead they capitulated to the tactics of Republican strategists like Grover Norquist, who proudly quotes Lenin’s motto, “Probe with bayonets, looking for weakness.”
