Back in the day, Oppenheimer was regarded with the Rosenberg’s and Klaus Fuchs. The left never forgets its heroes.
They were celebrated hero's of the Left because they betrayed America and gave the Communist USSR the nuclear bomb.
Yet the Left defended the Rosenbergs publicly and loudly proclaimed their innocence for decades until the disclosures after. the fall of the Soviet Union proved their guilt beyond any shadow of a doubt.
Some on the Left still proclaim their innocence, even after the proof has been out there for 30 years.
Amazingly, the Russian intelligence operative that worked with the Rosenbergs was furious that anyone could doubt or deny the Rosenberg's role in giving the USSR the knowledge and technology to build nuclear weapons.
To him, the Rosenbergs were brave Hero's of The Soviet Union who gave their lives for the cause and should be celebrated and given full credit for their invaluable contributions to the USSR.
