I would have hoped the world moved on to post-nationalism by this point. I can't say I had much hope for it, though.
I don't know if it's right to link all the countries which seem to be heading toward a more nationalistic government together, though. I think each case has its own causes and conditions.
For example, in some parts of Europe, it's the real or perceived threat to national security, and lots of reporting on terrorist attacks, and party leaders knowing how to take advantage of this.
What's the cause in Japan? Could it be that there's fear over what's happening in Europe, or could it be a threat from China, or something else completely?
The question is interesting to me, as I'm a wannabe immigrant. What would life be like if the trend continues? As I said, for my own wellbeing and happiness, I would have hoped we'd be heading toward post-nationalism. It's as if the "us and them" divide in Japan (this is the only country I know of) wasn't strong enough already.
