Is the UK occupied by Russia due to the botched assassination of Sergei Skripal using Novichok nerve agent in Salisbury in 2018?
Is Pakistan occupied by the USA because of the US Navy Seals who killed Osama Bin-Laden in 2011?
I assume US special forces are present in many places from time to time if not continuously, although they are also continuously based in many countries.
I assume all serious countries have spies in every single other serious country. If you exclude small and poor countries, everyone occupies everyone? How is this definition useful in any way?
