questions for and topics discussion
Questions for and Topics Discussion ...
  • Do you think that the provisions for water allocations should be changed? If this were the case, what kind of changes would be appropriate?
  • The resources of US and Mexico for solving problems at the border are disproportionate. Do you believe that this could hinder the improvement of the border conditions? What do you suggest to handle this situation?
  • Should US act unilaterally to try to solve the whole problem? What kind of consequences could be derived from this action?
questions for and topics discussion1
... Questions for and Topics Discussion
  • Mexico want to solve the common problems at the border but frequently faces internal economic, social, political and legal constrains. Can you imagine a multilateral entity or mechanism to help the country?
  • From the point of view of many Mexicans, the United States have historically shown on many issues a rather arrogant or dismissing attitude with its southern neighbor. Have you ever thought on that? If it were the case, what signals might the United States send to Mexico to change that perception? How Mexico might contribute?
