The U.S. military and CIA are intensifying efforts to combat Mexican drug cartels through covert operations, including the deployment of advanced surveillance aircraft and drone missions. As secret drone flights expand over Mexico, officials indicate a growing military presence along the southern border aimed at tracking cartel activities, including the location of drug labs. The Mexican government has expressed concerns about the potential implications of these surveillance operations, stating uncertainty over the actions of U.S. planes and calling for clarity. Meanwhile, under the Trump administration, plans for a larger role for the CIA in the fight against drug cartels are gaining traction, raising questions about potential covert actions and their impact on border security.
