As has already been correctly pointed out, this does not always take place in public, because that does not always produce the desired effect – sometimes silent diplomacy is better – but it does take place, and regularly.
Som det allerede korrekt er blevet påpeget, sker dette ikke altid offentligt, for det giver ikke altid den ønskede virkning - undertiden er stille diplomati bedre - men det sker, og det sker regelmæssigt.
