If you want to see what some of the least liked countries are in the world, this is perhaps the easiest way to do so. The countries highlighted in red on this map did not receive an invitation to attend the funeral of Queen Elizabeth II. As you can see, the majority of the world's countries did receive an invite, however, there were some major exceptions like Russia and Iran.
It's pretty obvious why these countries were not invited to the funeral and there is no way this could have come as any shock to them when the invites went out.
