The US Department of Homeland Security (DHS) is facing a range of diverse and complex security threats, from cyberattacks that disregard borders to what the Biden regime is saying is triggering mass migrations to the U.S. Secretary of DHS Alejandro Mayorkas highlighted this in an interview with Christiane Amanpour on Tuesday broadcast on CNN International’s “Amanpour”.

Amanpour asked, “Obviously, the other big issue is your border. Many of your opponents call it a border crisis. Do you consider it a crisis in the Biden administration?”

With regard to the US-Mexico border specifically, Mayorkas noted that the challenge it presented was one shared by many countries in the hemisphere and beyond. Colombia, for instance, is currently hosting 2.5 million Venezuelans within its borders, while Costa Rica’s population is increasingly comprised of Nicaraguans.

But one of the driving factors, according to Mayorkas, is apparently climate change.

Mayorkas responded, “Christiane, the issues that we have are extraordinarily diverse. I spoke about extreme weather events. I spoke about cybersecurity. You and I have now exchanged about the threat of adverse nation-states that seek to infringe on our and other countries’ sovereignty. 20 years ago, when our department was created, it was the foreign terrorists. We now have the challenge of domestic violent extremists. When we speak about the border, we have to put it in context that this is not a challenge — and it is indeed a challenge — not a challenge exclusive to the United States. Chile just deployed its military to its border. Colombia has 2.5 million Venezuelans within its borders. Costa Rica’s population is increasingly Nicaraguan. We are seeing a movement of people throughout the hemisphere and, quite frankly, throughout the world, that is historic. It is, for us, no question about it, a very serious challenge and a challenge that we are addressing with policies that stay true to our value as a nation of laws and a nation of immigrants.”

This one thing is apparently the cause of all that’s wrong in our world according to the left. It has become the new boogeyman.
