72% of the worlds nations are coming across the Mexican border! OK, I am watching Senate Judiciary  Hearing on Border Security right now and they were just asked if they have caught  any Chinese citizens coming across the border illegally. In answer, The guy says "Well, we have documented people from 140 countries, so I'm sure China was one of them". A quick search shows we only have 195 countries in the world right now. That means approx. 71.8 percent of all countries!   I don't think I have ever seen it put into context this way, so there ya go! I wonder what countries have NOT had someone?
