There is often the issue that these right wing cells are without their knowledge governmental “stay behind” cells who are operating somewhat under the jurisdiction of factions of the US government who are legally barred from operating clandestine missions on US borders.
What factions of the US Government are barred from operating clandestine missions on US borders?
Seeing that immigrants who are members of political extremist groups are barred from having permanent residence in the US, while registered spies are not.
Letting people who are spies live in our country doesn’t sound like a very good idea. Am I missing something?
