Mike Esper, secretary of defense under the wrecker, reports that the wrecker wanted to fire missiles at Mexican drug labs.

Aside from the outrageousness of this act of war, I don't think the US could have located them accurately enough to succeed in destroying them that way. And I suspect each missile would cost a thousand times the cost of a drug lab.

The department subsequently tried to block Esper from mentioning this in his book, but backed down. Esper suggests that it was acting politically, trying to protect the wrecker rather than the US.

The wrecker did so many provocative things to Mexico that the idea of trying to protect the US's relations with Mexico by concealing this proposal seems silly to me.
