Australian politics
Imagine that you first found out that foreigners hate Australia when you were about 12. Since then that's always been in the wings as you encounter non-Australians. For the most part they hate you.
They moan and moan year after year about how ugly you are, how everything Australia does is fucked up, how the world would be MUCH better off without you, on and on and on, endlessly.
Then one day Australia feels like it's time to bounce off the global stage. Some native isolationism starts kicking. Now what do you hear?
They're moaning because Australia used to be reliable. They used to be sane. They used to save hundreds of millions of lives on the regular. They used to be there to defend us. And now they're GONE! Do you think you might be a little bemused? Anyway, the US never had any responsibilities.
