North Korea attacked South Korea, more or less. After they starting building more nukes. Let's see how this pans out, but there's a good chance that this will result in WW3. Finally. Maybe all the 'US vs China' imaginary wars we've been thinking about all these years will turn out to be a lie and it will be more along the lines of 'World vs North Korea - Part 2: The Indians get bored and side with Korea' or 'US vs North Korea: How we fucked up the world and now nothing can survive on the surface'. Not that fun though, Australia is yet to have our F-35s delivered so we can't really get into a good fight at the moment.
