Not surprisingly, Mexican officials do not approve of Trump's ridiculous, illegal plan to deport non-Mexicans to Mexico.
“It’s a non-starter,” a Mexican official familiar with the situation said, switching to English for emphasis. The rest of the conversation took place in Spanish. “I don’t see a scenario in which Mexico accepts this solely because an executive order from the United States says so.” [...]
“I want to make clear in the most emphatic way possible that the government of Mexico and the Mexican people do not have to accept dispositions that one government wants to unilaterally impose over another,” [Mexican Foreign Minister Luis Videgaray] said.
Unlike Trump and those who serve him, Mexican officials actually have some measure of self-respect.
Secretary of State Rex Tillerson has been dispatched to Mexico to "mend fences," or whatever, but this is clearly a waste of his time. It's not clear to me what Tillerson even does at this point. Ostensibly, he's America's chief diplomat, but he seemingly has no authority and barely even has a direct line to the White House.
There's very little Tillerson can do while Trump and the White House draft policy papers without any input, and Trump himself can easily erase months and even years of diplomatic progress with a single tweet.
Tillerson himself must be wondering what purpose he serves. Even if you accept the premise that he took the job so he could cut deals with Russian business interests, it's possible he won't even be able to do that. Ironically, the Trump regime's cooperation with Russian intelligence during the campaign may be exactly what prevents Tillerson from cutting deals.
