I don't get the aluminum tube cartoon.
Neither do I.
I wonder if anyone does!
It's paraphrasing "Gone With The Wind", where the young slave girl, whose name escapes me,plaintively says, "I dunno nuttin' 'bout birthin' babies, Mz. Scarlett."
It's also a reference to her 9/11 commission testimony.
They are implying that she doesn't understand enough about nuclear weapons (that use aluminum tubes) to be able to effectively negotiate and work to remove them from rogue countries. In other word, they imply that she is to stupid to be Sec. of State.
