Six million jobs in the US depend on trade with Mexico. Ten border states - six in Mexico and four in the United States - combined have the third or fourth largest economy in the world. Twenty-nine US states depend on Mexico as their primary export market.

To the extent that President Trump means strengthened border security, I am fully in favor of the idea that the rule of the law, secure borders and public safety should prevail. Drugs should not enter illegally. Migration should take place in accordance with lawful norms and secure and safe procedures.

The work the Mexicans are doing in terms of migration control on Mexico's southern border is crucial to our own border security.

Indeed, many of the illegal crossers who have entered the country in the last two years after being detained have actually been either unaccompanied minors or families who request political asylum. The ability of the smugglers to attract large numbers of families and unaccompanied minors is a function of the inability of our immigration court system to process asylum claims in a timely fashion.

America should be working more with the Mexicans to prevent the flow of guns going south into Mexico that have fueled so much of the violence there, and the smuggling of cash and the money laundering that transnational criminal organizations have instituted in North America, including in the United States.

Until we have a legitimate labor market between Mexico and the United States, people will attempt to come here to work.
