...let the mexican people and the mexican government fix their own problems.

Absolutely. If they can not survive at their current level with their current economy, let their population decrease to a level that their country can support. To leach and steal from MY country to falsely support the people/economy of an obviously unfriendly different country is, to me, EXTREME justification of overt acts of war.

Exterminate the "excess" Mexican population? Sounds familiar.
