I agree entirely. KC3 can't stop them from going where they want to go, but it is clearer than ever that they are loose canon and capable of doing much damage at a diplomatic level.
KC3 and the grey suits need to do what they can, both behind the scenes quietly and in public actions, to control this situation.
If the Head of State doesn't have enough pull and power to make it clear to friendly nations at least that you don't give this pair the Royal Tour treatment and we'll be bl@@dy p1ssed off if you do, then what use is he?
