Hawaii isn’t its own country, it’s a US state (and not a territory like Puerto Rico, for example), so it’s been integrated into the American empire and independence isn’t likely. I don’t know if it could survive as an independent nation or if residents want to try though.
They’re okay, but they mostly taste like Vanilla Coke with a faint whisper of artificial chocolate flavour (think Tootsie Rolls). I really don’t recommend it unless you want to try a novelty flavour for fun.
