[Hunger Games] How did the US turn into Panem?

How did the US, a democratic super power both militarily and economically, fuck up so bad to the point where they're now an authoritarian dystopian nation? Also how do they interact with the rest of the world? Does the UN condemn this new governemnt?

The US didn't turn into Panem directly.  There was some sort of global catastrophe that more or less destroyed modern civilization as we know it, and the US was destroyed as part of that event.  War is always an option, and climate-change and accompanying sea-level rises is hinted at in the histories.  

Whatever the disaster, Panem rose out of the effort to rebuild society after the event.  It's not uncommon for fledgling nations in such harsh conditions to be authoritarian.  That's often the only kind of government that will work in that context.  And, of course, once such total control is no longer strictly needed, authoritarian governments have a long and storied history of going dystopian rather than relinquishing power to a more appropriate form of governance.
