Because the cartels are, and have been orchestrated by the CIA. Since way before Biden. They are just another form of secret army the CIA helps. Keep the South American and Central American nations unstable, keep allowing Marxist dictators to keep those nations weak, create sanctions against those governments at the price of starving out the people, the people come here, among them more cartel members sneak in under the guise of escaping the cartels. Eventually the cartels cause mass instability in this country (USA), and martial law is enforced. That would be my answer.
