Troubling reports reveal a Trump administration push to propel a failed war on drugs into a reckless, devastating war in Mexico.

Make no mistake: This is how dangerous ideas turn into deadly policies. How do we know? Earlier this year our sister organization, the Win Without War Education Fund, brought a team of former defense, diplomatic, trade, labor, and civil society experts, among others from the United States and Mexico to Capitol Hill to run a tabletop exercise to find out exactly what the outcome of U.S. strikes on cartels in Mexico would be.

The result? Chaos, violence, and harm. Even a “limited” U.S. strike would trigger events ranging from a trade war, mass displacement, a crackdown on civil liberties, and a rupture in diplomatic relations. One thing had not changed: The amount of synthetic drugs crossing the southern border.

Trump’s moves won’t halt the drug trade or help families struggling amidst a fentanyl crisis but they will increase violence and displacement within Mexico and ruin the critical, mutually-beneficial cross-border relationship.

Luckily, Representative Joaquin Castro has just introduced a resolution to oppose this deadly policy drift by affirming Mexico’s sovereignty. Congress must act swiftly to pass it and pull us off this misguided path to war.

We’re organizing people across the country to join us in telling every member of Congress to cosponsor and pass the resolution immediately. Will you speak out now?
