I voted yes. There has to be the price for changing the history.
And I think allies should not have this option at all. Or at least PP penalty for Allies has to be enormous.
P.S. I'm in July 1943 playing allies against AI and have more than enough Lightnings, Hellcats and Corsairs to wipe the table by Jap air force.
OOH, you are going to piss off the Allied boys with that suggestion. But I agree, they do not have to fear FUBAR'ing their production.
