The reason being is that Axis and Allies is geared toward the Allied player(s). Of course none of those disadvantages measures up with what my darling little England has to face, but I leave that to a different story.
From what I have seen used against me, I definitely suggest unlocking Russia restricted, 2-hit battleships, rockets and jet fighters, and A&A:E strat. bombing to even out the sides a bit. But feel free to use whatever sub-sets suit you best.
Sir Yanny, we [American] never lost Vietnam, the South Vietnamese did.
The fall of Saigon happened 30 April 1975, two years after the American military left Vietnam. The last American troops departed in their entirety 29 March 1973. How could we lose a war we had already stopped fighting? We fought to an agreed stalemate. The peace settlement was signed in Paris (notice why all treaties are signed in Paris?) on 27 January 1973. It called for release of all U.S. prisoners, withdrawal of U.S. forces, limitation of both sides’ forces inside South Vietnam, and a commitment to peaceful reunification.
