Military Intervention in Mexico?

As I've noted before, we have been at war with Mexico off and on for 150 years or so. It looks like that war might be heating up again. Fox News reports that "Trump calls for 'war' against Mexican drug cartel 'monsters' after Americans murdered." The article reports:

      Officials say at least six children and three women, apparently all U.S. citizens living in a community of Americans in Mexico, were gunned down after their convoy came under fire during a daylight ambush Monday. Six children were found alive, five of whom have been taken to hospital in Phoenix, Arizona. One child is currently missing, and authorities are searching the mountainous area on the Sonora-Chihuahua border for the child.

     Those attacked were members of the LeBaron family, a well-known American clan who has lived in the community in the northern part of the country for decades, according to The New York Times. The attack targeted citizens who live in a community founded as part of an offshoot of The Church of Jesus Christ of Latter-day Saints.

     "This is the time for Mexico, with the help of the United States, to wage WAR on the drug cartels and wipe them off the face of the earth," Trump tweeted. "We merely await a call from your great new president!"

The one thing that would unite Mexicans against the U.S. would be direct military intervention by the United States.
