The greater condemnation must go to administrations and lawmakers prior to Trump who created the illegal alien problem over the decades. Refused or unable to solve it. Let the problem grow and grow until they have this monster of a problem. 

And until a Trump comes along and use a guillotine to chop heads off. 

Trump says a country who cannot control its border is not sovereign. I say to Trump a country who cannot get rid of foreign military forces as the U.S. imposed on it is not sovereign. Sooner of later a Trump-like leader will come along and guillotine off American G.I. in his country.
