The reason the anti-drug operation is being discussed is because of the number of anticipated deaths from drug overdoses anticipated due to increased unemployment, hopelessness, and general depression due to the virus.
This is Trump trying to get ahead of drug use inflicting more damage as collateral to the virus. The cartels increased activity anticipating a growing customer base. This operation is to stomp on that before it can start.
Cartels are smugglers, or at least employ some of the best smugglers in the world. They’ve been used to bring terrorists into this country for years, and get big $$ for it. With the country in its weakened state, we’re ripe for an attack, possible some intel came down about certain folks making their way over here with possibly certain materials in tow and the Op needed to be disguised and acted upon immediately, so, drugs are bad speech.
