The problem with that premise (other than the nukes) is that the modern ship would run out of ammo rather quickly. Have fun threatening Joe Stalin’s 6 million man army with a single carrier’s ammo - we’d kill them for a few hours, then our planes would be useless except for surveillance (not that it is useless, of course).
Ditto with bringing back a company of Israeli special forces to defend the Temple against the Roman assault - they probably couldn’t carry enough ammo to kill all of the Romans in 2-3 legions, and would have to count on dispersing them after killing a few hundred or a couple thousand...but Roman soldiers of that era were highly disciplined and didn’t run off so easily.
Personally, just having a sniper each plug Hitler, Stalin, Tojo and Mussolini from a mile or more away with a .50, and then be evac’d with a modern chopper covered by modern fighters would do lots to change the outcome of the War.

Yeah, eventually you’d have to find a way to finagle a modern fighter to carry 1940’s machine guns or bombs if you wanted them in the fight for any length of time.
But like I said, you’d also run into the problem of maintenance and spare parts (which you wouldn’t have) when things eventually stopped working at 100% efficiency.
You’d have to go hard and end it quickly, which they would be capable of doing.
In my scenario of a carrier task force there’d be plenty of nukes available. Plenty enough to end the war.
Carrier would have nukes.
Some of the escorts would have nukes.
The attack subs screening the task force would definitely have nukes.
It would be a short war that would be over before the task force ran out of fuel.
