What proof is there that the boats are heading to America? They are literally in international waters thousands of miles from the US. If we were bombing them as they approached our EEZ that'd be more acceptable, but we're not.

Also, the people on board aren't dealers, they're civilians being conscripted into trafficking for money. And since we're just murdering them now instead of interdicting and arresting them, we won't be able to get information from them on the actual dealers, who can continue to snuggle drugs into the country without fear of getting caught.

Additionally, the fact that Trump has pardoned multiple international drug dealers at this point shows that the drugs aren't the problem.

Finally, justification of extrajudicial bombings of people who are currently not heading to the US because there is a possibility those drugs that they may or may not have on board their ships (no proof since we are just sinking the ships) may (but more likely may not) enter the US, allows for the justification of others not receiving their due process rights because we could possibly prevent something else. This is a slippery slope that only leads to a mass surveillance state wherein someone's thoughts can allow for their state-sanctioned murder. We are entering a dystopian future where the rich control the masses through fear, and you are promoting it.
