Respect sovereignty of a Nation and her borders. Otherwise, Mr. Ambassador, your existance as an ambassador is null and void, making your opinion moot and worth less than your dogs latest pile.
This is beyond cynicism, the governments of Mexico and Central American are involved in human trafficking and the illegal exportation to U.S. of minors under inhuman conditions, and now they have the gall to insult and menace the American people by demanding that the U.S. bestow the rights and privileges of its citizens to the illegal migrants (rights their migrants do not enjoy in their own country). All the while, those governments promote a massive invasion of the U.S. in gross violation of our sovereignty and international laws.
In addition, the demands of the Salvadoran Ambassador are beyond the pale. The Ambassador happens to represent the terrorists of the FMNL a group currently in power and the Salvadorian Maras Salvatruchas the most brutal gang of murderers who continue to extend their reign all over the U.S.
The U.S. government should demand that the countries where the illegal migrants came from pay for the care of their illegal migrants and for the expedited repatriation to their country of origin.
