If a modern US aircraft carrier task force (because carriers don’t move around alone) did find itself around 300 miles northeast of Hawaii on December 6, 1941 I expect they’d quickly determine their temporal displacement.
Then they would likely contact Pearl Harbor to alert the Navy of the impending Japanese attack. This would be done convincingly with a helicopter and a flyover by F-18 Hornets.
If the Admiral in charge of the task force was audacious enough he’d have F-18 fighters perform another flyover but this time of the Japanese forces and then contact the Japanese fleet in the clear and let them know they had lost the element of surprise.
The Japanese would retreat.
The US would then be in a position to dictate peace in the Pacific and soon enough the US would dictate peace in Germany...perhaps by using a nuclear weapon on Berlin.
Russia would then be ordered to retreat from Poland and the Baltics because the task force would invoke Article V of NATO to defend our (future) NATO allies.
And millions of the best American men would have lived and the leftist scumbags who took over their jobs in the public schools could be rooted out and dealt with to prevent them from hurting our country.
One can dream, right?
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.
Outstanding alternate history. What a marvelous dream of another universe’s reality. Especially not having the useless Boomers who have been spoiled brats of the Great Generation- whiny socialistic little brats (now quite old and they vote for Bernie! cause he’s like the grandparents that had to raise them).
Would love to see this as a script, and story boards. The thought alone of the lives that would have had families— and inventors and a much different outcome through today.
