Command & Conquer: Red Alert 3/Fridge

Fridge Brilliance

 * How does the death of Einstein lead to the rise of the Empire? Note that in Red Alert 1, the Americans seem to be absent from the Allied forces, while Red Alert II has the USS Arizona memorial. In the original Red Alert timeline, the US was busy fighting Japan on it's own, but in the altered timeline, the US either had to split their forces helping Europe, or concentrated their attention there. Either way, this meant the Empire had the time and space to build itself stronger.
 * The Empire of the Rising Sun's lack of a dedicated aircraft production structure unlike the other factions and reliance of Transforming Mecha units (Mecha/Jet Tengu, Striker/Chopper-VX, Sea/Sky Wing) for air power instead may appear odd until you realise that the Empire is based on Imperial Japan, which did not possess an independent air force and which instead maintained two air forces under the command of the Army and the Navy respectively.
 * Though the United States Air Force didn't achieve independant status from the Army until 1947 either, so Imperial Japan wasn't alone among the major belligerent powers in World War II for not having an independent air force. That said, the US Army Air Forces had wrested a substantial amount of independence from the Army, while its Japanese equivalents were on a much shorter leash.
