Japan is planning to spend roughly a quarter trillion USD over the next 5 years improving its military posture (archived). This move comes 73 years after Japan demilitarized following US threats to continue the nuclear bombardments which had already devastated two Japanese cities at the time. In recent years Japan has diversified their self defense forces adding an amphibious assault corps to defend their numerous outlying islands as China and both Koreas have presented aggressive military postures towards Japan.
At the same time the US military's presence has faded globally, to the point the product of exuberant fiat outlays appear to only allow the US to marginally prolong wars without impacting their outcome.
