It would've almost certainly required swift, decisive action - and crucially, they would've had to nuke the Soviet Union to end communism there.
First point, correct; Second, debatable.
The 'bankers' and the Jews high up in both the US and the UK both vetoed any such plan....Their plan was for the destruction/neutralization of Germany as a European power, and the continuation/expansion of the Communist gangster system in both Russia and Eastern Europe...Plus, the establishment of the Zionist state in Palestine.
The use of the atomic bomb was a 'scare tactic', purpose being to establish a 'World Organization' that would control all nuclear weapons...Who better to test this on than the defenseless Japanese, who were ready to surrender.
