USA actually brought nothing on this last century but the destruction of the world. The whole middle east situation is entirely their fault. The overwhelming power of oil companies is their fault. The absurd market deregulation is their fault. The nonsense power of banks on the rest of the world I their fault.
But you can also add instability of south America, consumption society, the absurd (and false) trust in a growth society.
I mean, USA is probably the biggest mistake of France. As a French I truly apologise, we should have never sent any troops and firepower to the USA when they were at war with UK. Sorry again people.
