Japan is #3? I thought we provided their defense. I would have never guessed. I thought they had something in their post-war constitution limiting their military size.
The Japanese economy is so huge that even going a bit above 1% of GDP in spending gives them a huge military budget.
Japan doesn't have a military. All they have is a self defense force. Of course, it takes a lot to defend yourself when you are face-to-face with China, North Korea and Russia.
