Also, would either Darth or Lizard mind explaining the exact terms of the Treaty of San Clemente, and why it prohibits South American nations from trading with Europe.
The clause of the Treaty of San Clemente that addresses your question states that Pan-American Alliance members agree not to import from non-member states, as to allow domestic/regional growth. A member state's imports come from other member states, IE the United States would import its rubber from Brazil, and Brazil would import its coal from the United States. This trade is not taxed.
If a member state wishes to do business with non-member states, it is required to be an export only relationship. This allows the member state to have full control over activities, which is a welcome change of pace from being exploited by Europeans for the past few centuries, where the peoples of the New World were exploited for resources.
If you have any more questions, feel free to PM me.
@ TheLizardKing - You appear to have slashed the quality of the Lexington-class greatly...and lowered its price significantly. We need to talk about this ASAP.
