Stop those illegal aliens from sending money back to Mexico and see if their politicans will continue to support the invasion of the US.
The notion of stopping the illegals from sending money back to Mexico would inspire the corrupt Mexican govt. to advocate more "aggressive" protests ie violence in the streets .
While the people of this country would demand the rounding up & deportation of anyone even suspected of being illegal you can feel safe in betting your next paycheck that the powers that be in the Congress would sell out this nation in a heart beat.
