(CNN) Our nation has a lot of serious problems. Living in a bad "neighborhood" is not one of them. But if we continue pretending it is -- arguing over border walls, deporting good kids brought here as infants by their parents, and deploying our military along the southern border -- we run the risk of making it so, or of at least failing to take full advantage of our geographic bounty.

The United States is blessed to have as neighbors two peaceful democracies that share our values. Canadians and Mexicans have contributed enormously to the American story since the earliest days of our republic, and remain steadfast friends despite having legitimate grounds to harbor the kind of irredentist resentment that stokes tension along many borders around the world. The United States acquired vast swaths of territory (my home of Arizona included) from Mexico in a war that a young congressman named Abraham Lincoln opposed as immoral , and yet for most of its history as a global power, the United States hasn't needed to deploy its military to secure its southern border.

Over the past two decades, the North American Free Trade Agreement has created the world's largest trading bloc, a vibrant, resource-rich economic zone that makes all of North America more competitive in the global economy. The integration of cross-border manufacturing within NAFTA has benefited our three countrie s, making us more competitive with low-cost producers like China.

Mexico in particular embraced dramatic change to join us in a North American community. Some of the changes were wrenching, especially for Mexican farmers and small businesses. Mexican government and society abandoned long-held anti-American grievances, to the point of amending the nation's constitution to allow US companies access to Mexico's oil riches, thus enhancing North American energy security.

But judging from American political discourse, you'd think trends in Mexico amount to a liability for the United States, instead of a huge asset. For example, White House chief of staff John Kelly recently told NPR that the "vast majority" of undocumented immigrants don't speak English, are ill-educated, and are "not people who would easily assimilate into the United States." Our current administration is breaking with its predecessors, especially its Republican predecessors, by threatening to abandon NAFTA (currently in the final stages of a renegotiation ) and is perpetuating outdated, if not altogether fabricated, narratives about Mexico.

And yet, from candidate and now President Trump and others, we hear and see portrayals of Mexico as a crucible of criminal activity poised threateningly to the south. It's easy for the rest of us to blame politicians for this lack of appreciation of what Mexico has become, but in some ways, all Americans are to blame for this failure. As the president of a university in a border state, I can see how outdated, misinformed stereotypes of Mexico that are commonplace in the news and in our popular culture represent a collective failure on our part as educators. In my role, I feel it's especially important for institutions of higher learning to build a greater understanding between both countries, not only by increasing the two-way flows of students across the border, but also by partnering with Mexican universities to conduct joint research projects on shared challenges facing our societies.

The immediate danger is that Mexicans, who will vote for a new president in three months, might grow disenchanted with their decision to align themselves with the United States, feeling betrayed by an American government that insists on treating them not as partners and friends, but as villainous antagonists. Polling data released earlier this year showed that for the first time in a quarter-century, a majority of Mexicans hold negative views of the United States. Mexicans are increasingly susceptible to anti-American politicians seeking to sabotage the relationship. It would be a tragic case of a self-fulfilling prophecy.

The vast majority of immigrants from Mexico, as is true of our DACA students on campus and has been true of immigrants from other parts of the world to this country for more than two centuries, work hard and make important contributions to our communities. They come from a neighbor that has become a great friend of the United States, and an important commercial partner.

We should be working hard to strengthen our North American partnership, not weaken it.
