It’s a preemptive attack to prevent accountability for Trump and Hegseth under the next presidency. All of those extrajudicial boat attacks that have been justified by claiming they were smuggling drugs (cocaine imports to the US haven’t dropped at all, BTW) are likely unjustified murders.
This administration attacks any body or authority that has the power to hold them accountable. See: attacks on the judiciary, attacks on the media, attacks on academia, etc.
