For one, the political climate in neighboring Mexico was extremely volatile. Agents of the German war machine were known to be active throughout Mexico (with the knowledge and consent of the Mexican govt?).
Nazi Germany was the leading importer of Mexican oil, taking just over half of their annual production....... To counter, American oil and gas production in Texas and Louisiana was elevated. Port Isabel's large oil refinery was a shipping point for fuel headed to the war, and was considered a possible target for German U-boat shelling or even a shore scurry.
Wowser---nice bgrnder, Dave---needs to surface everytime sap-happy Obama gets on his knees and puckers up to illegals.
I guess when Texas Gov Perry was honored by Mexico for giveaways to illegals---and when he told nay-saying Rep primary voters we didn't have a heart----he knew n-o-t-h-i-n-g about Texas-Mexico military history (/snix).

BTW, I came upon the Mexican/German connection through published stories about patriots---Hollywood actress Rochelle Hudson and her husband ......they became undercover agents who posed as tourists and discovererd that Mexico was the site of German activity and that a supply of high test aviation gas was hidden by German agents in Baja California....a Mexican outpost.
also during WWI Mexico had secret letters going back and forth from Germany...
