The US government is not supposed to murder US citizens. But they could make a list of “inconvenient” people, pass it to the British, and decline to act if Brits do the work.
And vice-versa.
Churchill and Roosevelt probably held a lot of very private meetings re their MI6 guys and our OSS guys’s updated and approved hit lists.
MI6 Code names: The Secret Intelligence Service (SIS), commonly known as MI6 (Military Intelligence, Section 6), is the foreign intelligence service of the United Kingdom, tasked mainly with the covert overseas collection and analysis of human intelligence on foreign nationals in support of its Five Eyes partners.
If it is ok for government officials to kill Americans, then is it ok for American’s to kill government officials?
