your challange should you choose to accept it is to have atomic annie or one of her equivelents used on a live hostile target... your pod can be anytime after jan 1 1946....bonus points if its not ww3 use
Perhaps, if Macarthur invades China but the Chinese Communists gain air superiority, the only way to nuke targets is with artillery. That's the best way I can see. It gets hard to justify nuclear artillery once the 1950s end.
Yeah Korea is your best bet, have truman let MacArthur take the gloves off, and once the atomic genie is let out of the bottle, you could get atomic artillery used in a combat situation, most likely against advancing chinese troops, however I don't see how this doesn't escalate into WWIII.
if maybe the chinese incursion into korea was sometime later after annie was finished developed i think it could happen... annie's production date would have to be moved up a little bit
