Terms "racist" and "xenophobic" could be badges awarded by liberals and multiculturalists. Something like Purple Hearts accrued by an enemy.
Accepting your point, it is precisely their closed culture that makes them so strong. I wouldn't presume to bring our own obnoxious baggage into their land, but instead to assimilate.
As things are now, pop-Japanese culture is plenty in love with Western concepts, and the Indian work ethic is, "how do you say, PLEASE HOLD WHILE I CONNECT YOU, MA'AM..."
"Yeah, but the Asians are smart enough not to let too many foreigners in."
Then we must incentivize their coming here. At least in bigger numbers than the present usurpers we face.
Here's hoping it won't come to that anyway. Even as strictly operational allies, they will be important, failing the exchange of our population as some desperate experiment to save ourselves...
I am neither. Also, the Japanese economy has been a mess for 15 years. They are going to continue to experience similiar growing pains to our own.
India, not China is the most likely to replace us as the global economic leader. But this will still take several generations.
Japan, has, for the past 70 years or more, taken bits and pieces of AMERICAN CULTURE as their own! They have jettisoned a lot of their own culture; mostly keeping the worst bits of it only.
