Basically impossible to take out Barbarossa. Policies and attitudes of the Hitler regime, especially Hitler, mean that is is unquestionably going to happen sooner or later.

Soviets would have had nukes sooner without a German attack. Same US intel, but no battle damage or massive resource/population drain.
