Well that is a good way for a diplomat to lose their job. Publicly criticizing the head diplomat of the country. Whether or not the criticism is valid is beside the point. One doesn't go around publicly criticizing the head of state. Now absolutely behind closed doors tell him You should be little more careful, that last public statement might not have been in the best possible tone.

Like it is kinda funny how he got sacked criticizing head of state for what might be interpreted as alliance disunity. While showing national disunity by publicly criticizing his own head of state. Yeah. That gets you fired.
