The problem I have with your objection is that England already does what you say and is still lost to Germany by round 4 (vs round 3 if they harras the Italians instead.)
The other problem I have with your objection is that the 10 IPC NO is already automatic for America since it’s virtually impossible for Japan or Germany to get E. USA, C. USA or W. USA anyway.
The idea is, if we move that objective to London, then America will lose that NO unless the dice go crazy, or they go liberate it. However, it is logical that the Continental United States should be worth something (I would actually lump Alaska in here, but they were not officially a state yet, so I’ll let that one drop) so giving that 5 IPC is okay with me. However, a Mexican NO? Sounds like they were hunting and searching for anything so as to give America more money, presumably because they thought America would need the cash for both hemispheres, but I cannot read minds and I was not privvy to the discussion at the time of creation. I suggest removing this NO entirely and moving it, along with half of the continental NO, to England.
American intelligence networks knew, quite well, that if England fell, breaching Europe and defeating Hitler was going to be almost impossible. They realized how evil “Unkle Adolf” was and had first hand accounts of concentration camps from escaped survivors (whether or not they believed them is a moot point, they had the reports, you can get copies from the government under the Freedom of Information Act.) Thus, America knew it had to save England, if only to have a stepping stone into France to win the war. That is not the case in this game.
Further, do not the justifications for these National Objectives all call upon the history of the political and military situation at the time? Mexico was hardly militaristic nor strategically nor even politically significant to World War II (I apologize to any Mexicans who are reading this, no insult is intended, but they were hardly under any threat historically speaking, nor were they a threat.) Meanwhile, as detailed above, the fall of London would have been a crushing defeat to the Allied aspirations of victory, yet there is no national objective for America to stop London from falling. There is one for Germany to take it, primarily because the fall of London would have assured them success, in the real war, or very close too it.
Granted, to judge the viability of the change, we would need test data.
