Don't be so childish. "destroying the world".
What can be done, very little, what should be done, again very little.
As long as what is happening in Brazil has little to no impact on its neighbouring countries, nothing should be done to Brazil, apart from some harsh words on twitter or facebook from the likes of you and your friends if it panics you, nothing should be done to stop Brazil doing what it wants to do in Brazil.
We haven't yet despite what some claim with their NWO (New World Order) clap-trap, got a world government.
