How would hist have been affected had Pershing's Punitive Expedition into Mexico managed to actually capture or kill Pancho Villa during the 1st 1/2 of 1916 ? Would Villa have inevitably, in American hands, been tried for his murder of American engineers on the hijacked train and for the raid on Columbus, NM, then executed ? Would Mexico have become more or less stable as a result of Villa being taken, and what about the security of the southwest border states ?
