Hello!
The new technology that allowed the Allies to more effectively bomb the Japanese main land, was the capacity of the B-29. If we look at the other ones, we see that all that stuff already exist before the war.
Hugs!
The Cold War Containment policy was a complete bust because we pour money into failing countries so they there economy was strong enough to where they wouldn't have radical thoughts of communism this was referred to as the Truman doctrine and then the Eisenhower doctrine that funded the middle east. Then we went into the police action "war" in Korea so that the domino effect wouldn't allow other nations to fall to communism
