Basically this: MERCOSUR/MERCOSUL is, in OTL , a Free trade zone that should have become a Common Market (it is even in it's name). Unfortunately, this economic bloc falled into stagnation and the Pacific Alliance is going better in South America. So, how could MERCOSUR and it's have done better economically and politically to prosper? And what new countries could enter in this bloc? And the other consequences (for the member countries and the world)?
