This is not just idle talk, they have already killed or seriously wounded a lot of officers around the country. in the very short time they have been in the country. They have also been involved in many rapes and murders, including a couple of high profile assaults.
They are in fact a criminal para military expeditionary force sent into the US so they obviously cannot be receiving any financial support from Maduro as that would be an overt act of war against the US.
They are implementing their Venezuelan model of brazen violent extortion and social control as we have seen in the Aurora apartment take over videos.
This allows them to take control of the streets, terrorize people into submission and also provide a lucrative Venezuelan Maduro style self funding mechanism for their subversion and Antifa like direct action political street violence to support Progressive Leftist agendas.
It is highly likely that both Tren de Aragua and Antifa are two sides of the same coin and take their direction from the same leadership.
Imagine what the next series of Antifa riots would look like if they had Tren de Aragua thugs armed with AK-47s instead of snowflakes and pedophiles armed with umbrellas, air horns and milkshakes.
This is what Trump was talking about when he discussed the "enemy from within" in a couple of interviews and the possible need for military action to put them down
They are not just simple criminals, they are part of a carefully planned effort to import the equivalent of the 1930s Nazi Brown Shirts into America to support the Progressive Left's agenda with anarchy and a type of politically directed aggressive hyper violence we have not seen in America since the Comanches in the mid 1800s.
Do you happen to know if they wear body armor?
