This is not surprising, especially with India and China. About Japan, IDK much so no comments.
Regarding Pak, credit to where it is due for bringing the resolution up. But dont forget, they also sold jets to Myanmar. However, I'd cut them a slack given the fact the JF Thunder is a joint China-Pak project. So there might have been pressure from China to sell it. I dont know. May be the Pakistanis can clarify further.
Moral of the story is, nobody is nobody's friend. We gotta take care of our shit and find trues allies instead of just 'friends' and 'strategic development partners'.
