Why are you even debating/trying to talk some sense to that Iranian immigrant my friend? Don't waste your time he wont listen. To him every thing every country does is because of the U.S .lool. So if you think you can convince him that Japan has its own interests and reason for keeping its status in Asia then im afraid you are fooling youself he wont listen.
Just like you cant ever convince his delusional mullahs that the U.S is not out there to get them .
I'm even surprise he and his parents ran away from his country when his mullahs took power and impose an islamic state, i would have expected them to stay put and enjoy the joys of the ummah, instead they opted to run away to the Evil west.
You will expect them to run away to KSA,UAE,Turkey, Pakistan, or any other holy islamic country, not the evil infidel immoral imperialistic west.
