US Military Intervention in Mexico & Other Countries of Latin America

Mexico is a sovereign state. Any kind of open intervention of the US army in Mexico will be a war. I'm Mexican and I'm sure the US army can crush the Mexican army in a few days, But I'm also sure an invasion like this will end in a tremendous defeat for the US in the long term. Mexico is not Iraq or Afghanistan, Mexico its the 11th economy in the world, One of the best commercial partners of the US and the second best market for US exports. Are the US ready to loose all those business? Are the US ready for a war against 130 million of Mexicans? Come on we are not in the 19th C. 2. The US army is designed to fight symmetric wars against other regular armies, In fact I'm sure the US army could hypothetically defeat any other army in the world, But let's be honest, The US army is not that good fighting asymmetric wars against small groups of irregulars mixed with local population and with no concrete bases that could be targets for air force strikes, Like the drug overlords and their "private" armies. What happened in Vietnam and what happened in Iraq and what could happen in Syria are good samples. In the hypothetical scenario where the US army cross the border and go directly against the cartels, It will became automatically in a source of interminable problems, The drug overlords will became a sort of "guerrilla" and they will become indistinguishable of the regular Mexican patriotic resistance; at the end of the day the US are not ready for face this kind of mess so close to the its border. 3. The US invasion of a close partner and ally, Like this will be catastrophic for the US international relationships. What kind of reaction will have the other NATO members? What kind of feel will Canada have? What about the reactions of the other Latin American countries, And the hypothetical support of the Chinese and Russians to the resistance. In the long term I think the US will end alone against the world, And I'm not talking only about political terms but also about commerce. Who will want to do business with somebody who invade a close friend and partner? 4. The US is supporting the Mexican army to do that job, In my opinion is a dirty job. The Drugs war is the main source of the violence in Mexico. The US just don't want to fight that war, So pushes Mexico to do it and bleed because that. In 8 years of war this has caused us more than 250, 000 casualties, Yes your read right, The Drug War has been more violent and terrible that the Vietnam war or the Syrian Civil war; have you ever hear about the "emigrants"? Ok they are the refugees of the drug war, Just the same as the Syrian who want to flee from the war civil. The only options this poor people have is became slaves or soldiers of the drugs overlords, Became a casualty or cross the border. If you were in their shoes what will be your choice? The drug overlords have a "product" to sell and this product have a high demand in the other side of the border and the profit of this business is huge, This means they have billions of dollars and with this money they can buy guns and political influence. The worst is in some cases the US government is not making them the things hard but is helping them like in ATF gun walking scandal. At the end of the day all this problem is a big hypocrisy, Because the US government is not doing nothing to stop the addictions or reduce the number of addicts. They believe the only option is fight with the sellers. The only solution is the legalization of some drugs and work in the prevention of the addiction of other. Today (Nov. 4 2015) in Mexico City in the supreme Court will be a serious discussion about the legalization of the Cannabis, The reasons: a) Is really stupid forbid the cannabis and allow the open sell of Tobacco, Alcohol and even sugar, Which are more addictive and cause more health problems and far more deaths. b) What is worst? Allow the farmers produce this openly, Pay taxes, Improve their economies, Have a governmental regulation? Or keep the illegal production leaving the farmers alone with the drug overlords to exploit them and the government to prosecute them? One way or another the US junkies will continue buying it.
