Aldo Moro (Italian President of the Christian Democrat Party) was threatened by Henry Kissinger in NYC in 1975 to not form a coalition govt with the Communists or he’d pay the ultimate price. In 1978 Moro did, was kidnapped and assassinated.
Not sure what is going on here, but outside forces could be applying pressure as they did in 1975.
Well, you certainly choose your facts selectively. The Soviets very publicly opposed the alliance, on the grounds that the Italian Communist party was drifting away from its influence. He was captured by the Soviet-aligned Red Brigades, who demanded the release of their founders. Italy refused, and he was executed. Suggesting that the Red Brigades did the work of the CIA is turning the universe upside-down.
