What aviation? The US air force was far superior to that of the Soviet Union throughout the existence of the Soviet Union. The Soviets at times might have had comparable machines. Even then, they never had better pilots. The UN had air superiority in Korea for all but the first few months of that conflict. A decade or so later in Vietnam, the Soviets were so overwhelmed in the air (and they knew it) that they didn't want to play the air warfare game at all.
Ballistic missiles? The first legitimate Soviet ballistic missile wasn't until a decade after the war ended. By that time MAD was already in full swing. There never was a missile gap; the US had the Soviets outgunned with respect to nuclear weapons from day 1. (Not that it matters much when each side had the ability to wipe out the other dozens of times over.) The Soviets feared the US as much as, if not more than, the US feared the Soviets with regard to a nuclear WWIII. Mad Ivan? The Soviets weren't mad, at least not in their minds. We were. The only way the Soviets were going to launch their missiles was if we launched ours first.
