What a billborad ! Talk about a pipe dream ! There is no way the Mexicans can take southern cal. Its not logistically possible. They might over run San Diego for awhile, but north of San Diego there are only a severely restricted number of passable highways. They consist of a coastal freeway, a mountain pass, and a vast desert. Defendable logistical territory was acquired by the feds over 100 years ago. Forces have been strategically moved into position for over 100 years now. The truth of the situation is that American forces already in place can overun Mexico just as fast as we did Iraq. Days to Mexico City, not months and not even weeks.
