There are two competing theories about how the Soviet Union collapsed.
One holds that Ronald Reagan’s moral leadership against communism and bolstering of US defences weakened Moscow’s will and buried them economically. The other contends that Mikhail Gorbachev’s domestic reforms and wise diplomacy brought down the Iron Curtain in spite of the cowboy in the White House. We can now add a third hypothesis: Jeremy Corbyn did it.
If the claims of a former Czechoslovakian agent are to be believed, the Labour leader was a paid informant for the secret police. That would certainly explain the devastating collapse of state socialism. Even the mighty Warsaw Pact could not have withstood the support of Jeremy Corbyn.
