Homeland security is inherently transnational today. There's hardly anything adverse that happens in our homeland that doesn't have a cause or effect that's generated abroad. Increasingly, we must rely on our allies and foreign governments to share information and data to secure our country.

People in our so-called Rust Belt have lost out, and politics and society have not been responsive either in providing the kind of additional support they need or to retrain them for jobs that are being created in the new economy.

We have to remember that information sharing is restricted by legal barriers and cultural barriers and by the notion that information is power and therefore should be hoarded so if you share information you can extract something in exchange. In today's digital online world, those who don't share information will be isolated and left behind. We need the data of other countries to connect the dots.

People should remember that Mexican migration is now at a net negative. More Mexicans are leaving through deportation and voluntary return than are entering the United States legally and illegally.

Every air traveler entering Mexico is vetted against US databases. The air passenger screening system Mexico has in place involves these checks against US national security and criminal data bases. There are plainclothes US officers stationed at airports in Mexico working with Mexican immigration officials to protect the United States. This joint security program has been in place for at least six years and is a huge asset.

The image and the costs of a Berlin-like wall or a Great Wall of China is something that the American people have not accepted to date.

The potential of Mexico, Canada and the United States is enormous. We have a combined population of half a billion people; peaceful trade-friendly borders that are the envy of the world; the prospect of energy independence is within reach and will change the geopolitical situation of United States; we do a trillion dollars in trade among the three countries; more than 18,000 American companies are involved in foreign direct investment in Mexico and Canada; an increasing number of Mexican companies are creating jobs in the United States.
