[Iron Munro]

Americans didn't "let" the nuclear secret out. Anyone who knows the history of the
post WWII era knows it was leftist spies who passed our nuclear secrets to the USSR.

[Sherman Logan]

The leftist spies meant the Soviets got the Bomb more quickly than they otherwise would have.

If there had been no leftist spies they would still have gotten it, would have just taken a little more time.

Unless you believe the laws of physics aren’t as accessible to commies as to anybody else.
