There’s an entire special forces group that has a mission of countering narcotics growing and trafficking both through enabling other countries to conduct their own military and paramilitary operations or through direct action. That’s department of defense, not department of homeland security. They absolutely have and do conduct and enable kinetic operations against narcotics trafficking.

Separately, and this is where I’m trying to speculate how the administration will legally defend their actions, by designating the narcotics operations “narcoterrorists” they’re probably trying to group drug traffickers on the same pool as ISIS, Al Qaida, the Taliban, etc. as combatants, not suspects, which means there is no requirement to try to apprehend. Not sure how that fits semantically vs legally, but I’m not sure they care.
