Oh ok, Japan will just go back to the stone ages because you said so....they are a sea locked land without great access to oil like us. Also, the closest oil for them is in the South China Sea and China is growing their military to prevent anyone from getting that oil in international waters....but I'm sure you'll make excuses for China too.
Any stoppage of middle east oil would harm the US economy, you cannot be that stupid. A major trading partner, Japan, would be crushed....but you don't seem to think beyond your nose.
If Japan is so much more dependent on mid-east stability perhaps Japan should decide whether it wants to involve itslef in the region rather than letting us do it for them. It's you who has no forsight. It's you who can't see past what would likely happen past your doomsday prophecies.
No idiot. Japan should take care of Japan. That the country has the geography it has does not make keeping their oil supply stable our responsibility. Or at the very least they ought to be paying us to secure their oil supply. As far China protecting the oil in can get that would be China taking care of China. Are you starting to get the picture yet?
