Apparently, there is such a thing as a Nationalist Kindergarten Scandal:
These commentators appear to believe there is something to this, but it sounds like typical international leftist behavior to me. Remember Pinochet, who was not allowed to live in peace after he voluntarily gave up power. No, they had to keep chasing him.
It is the same thing here, it seems to me. Abe's overtures to Trump were, to the left, unacceptable, and thus they create a narrative about a scandal that is also unacceptable- largely to themselves. You can see these commentators think it's a big deal; you can also see they don't take Trump seriously either. So they are quite likely to be misreading the Japanese public as well. The Japanese media can, just like the American media, continue to blare all kind of nonsense; what matter is the opinion of the people. In America, at least, Trump appears to be winning this war. It is going to be a long war, and fraught with complications.
No doubt someone will attempt to mire Theresa May in scandal as well.
