President Trump wants to deploy a blunt new tool to fight Mexican cartels that flood the U.S. with drugs, by adding them to a list of terrorist groups that includes the likes of al Qaeda and Hamas. The move could increase pressure on the cartels by directing more money to intelligence gathering.

President Donald Trump's order designating cartels as terrorist organizations may be getting overlooked, but it will increase U.S. security.

It is difficult to determine how these heterogeneous crime groups target the United States, but Mexican authorities need to respond to what might be called domestic terrorism.
