Donald Trump campaigned on securing our borders and getting tough on illegal immigration.

And since taking office, he has made good on his promise by issuing guidance memos instructing the Department of Homeland Security to enforce immigration laws accordingly.

But Mexico responded to Trump’s crackdown on illegal immigration with a major threat.

Trump’s memos outlined his administration’s plans to stop illegal immigration as well other aliens who abuse America’s welfare system or commit crimes.

Politico reports:

“President Donald Trump pledged during his campaign to create a deportation force. Now, he’s equipped federal immigration agents with the tools to potentially remove millions of immigrants from the country.

The Department of Homeland Security issued a pair of guidance memos Tuesday that gives federal immigration agents wide latitude to arrest, detain and deport undocumented immigrants and legal immigrants with criminal records.

The memos create a blueprint for how to enact two Trump executive orders, one that deals with interior enforcement and another that deals with border security.

Serious criminals will still be a top target for federal immigration officers. But the priorities will be greatly expanded to include undocumented immigrants charged with crimes or those who have committed acts that could constitute a chargeable offense.

The Trump administration’s deportation push will not be limited to undocumented immigrants. The memo stresses that all “removable aliens” could be subject to immigration enforcement under the new guidelines.”

And Mexican officials were furious with Trump’s order.

They have grown accustomed to American leadership welcoming illegal immigration.

So when Trump ordered federal agencies to enforce immigration laws and deport dangerous illegal immigrants, Mexican officials responded with an outrageous threat.

They flat out refused to accept Trump’s order.

The Hill reports:

“Mexico’s lead negotiator with the Trump administration is slamming new rules that call for deporting people living illegally in the U.S. to Mexico, regardless of whether they are citizens of that country.

“I want to say clearly and emphatically that the government of Mexico and the Mexican people do not have to accept provisions that one government unilaterally wants to impose on the other,” Mexican Foreign Minister Luis Videgaray said Wednesday, according to Reuters.

“We will not accept it, because there’s no reason why we should, and because it is not in the interests of Mexico,” he told reporters at Mexico’s foreign ministry in Mexico City.

Videgaray added the “unilateral” rules would likely dominate talks between the U.S. and Mexico Wednesday and Thursday.”

Mexico’s indignation about being forced to take back their citizens is a direct challenge to United States sovereignty.

If America cannot protect its own borders and enforce the conditions for becoming a citizen, then it is no longer a nation.

If Mexico is allowed to dictate who can remain in America and under what conditions, then they become in charge of American citizens.

And that’s a dangerous concept.
