Nuclear weapons discovered after WWII

What if nukes just weren’t discovered until after the war, either the Manhattan Project took longer, or wasn’t started until later on in the war, or even after?

Say Japan surrendered because of conventional firebombings and starvation.

Does the Cold War even play out in the same way if nukes remain a hypothetical weapon until later on? Will the West-East animosity be more blatant and less restrained? Will tactical nukes be normalized until after they’re used in combat for the first time?
 
Anything could happen if the development of nuclear weapons get delayed for whatever reason. Maybe even WWIII breaking out between the USA and USSR, probably around a couple decades after WWII. If nukes get invented later on by the USA or another country, then they inevitably will be demonstrated in warfare just to show what they're capable of.

No, yes and yes. The only reason why the Cold War remained a war of words and geopolitical influence was because of the power of nuclear weapons. Without those weapons, World War III could've broken out during the Cold War. And I do believe if nukes are used tactically by one side (similar to what MacArthur wanted to do in the Korean War), the other side might resort to the same methods.

Honestly with out the nuclear edge.. Ww 3 may be sooner than later, not due to only the soviets but the west acting like asshats as well to the east and the sheer idiological wall of power hungry megalomaniac who don't care if millions die.

Ww3 starts like in 48 or 49 or maybe even sooner or as history Woukd write it.. Ww 2 never ended it just switched partners
 
Also.. No nukes for Ww2 means that when they are used they are used like bubblegum at a kids playground for a while.. Especially if Noone else has them... until it is shown that while they work.. They work too well on large metro or military concentrations but leave the area screwed for further occupation and the innocents mangled and mamed.

Or look why am I dropping a Nuke on 3 tanks
