I believe that there’s a word for a situation in which munitions are fired across an international border aimed at troops defending that border. It is a “war.” Fox News’ Bill Melugin — the preeminent journalist on the story of our southern border — captured video of tracer rounds at night coming across the Rio Grande and the taunts that accompanied them. […] The automatic weapons fire directed at National Guard soldiers is not coming from the armed forces of Mexico, but rather from the cartels that constitute the de facto governing force of major parts of Mexico. If Donald Trump were still in office, I have no doubt that he would be on the phone with Mexican President Lopez Obrador telling him that either Mexico ends the attacks on the United States or he will. Yes, that would involve weapons like predator drones or fighter aircraft (A-10 Warthogs can unleash hell on anything on the ground) or even artillery. And no, it would not be an attack on the sovereign nation of Mexico but rather on terror groups it is unable or unwilling to suppress. President Trump would explain this and no doubt would first offer the President of Mexico the role of ending the attack.
