^ Only a question of time before nukes, airpower (manned or otherwise) & tanks are all redundant. All it'll take is for weapons to be carried in space both for defensive (take out nukes in flight ~ similar to original US SDI programme) and offensive purposes. The Chinese have already destroyed a satellie from the ground (2007) and the military funds/runs its space programme. They show little interest in teaming up with NASA, RKA & ESA. The 13th man to walk on the moon is most likely to be Chinese.
