If you mean in the 1930’s and 40’s, the answer is; it probably wouldn’t have helped anyway, given the world as it was then.
If you mean the difference of opinions there is between them today; definitely yes. Times are different and the way people think about relationships between countries are different.
The scare mongery created by the military/industrial complex is self serving, but less and less people buy the theory that everything can be solved by guns, or by gunboat diplomacy.
Not perfect by any means, but it is highly unlikely that Germany would attack Poland, or Japan attack China today. Likewise, that Russia would attack either USA, or any other NATO country.
If noting else, because all the major nuclear powers (USA, Russia, China) are fully aware that starting a war against each other would be “mutual assured destruction” (MAD), or at least too costly to be considered.
Let’s hope that no madman in either one of those countries get in a position where he could “hit that button” alone, without checks and balances.
