The King has shown he is not afraid to use glanz und gloria. The start of his Reign with the festivities around April 30th were incomparable with that of his mother, who was Inaugurated in a city turned into a war zone. I think the King and the Queen will make fullbblown State Visits. I am not afraid for that.
I have the idea that the three quick visits to Luxembourg, Germany and Belgium are all done because these three countries were very recently visited by the Queen:
Luxembourg:
Germany:
Belgium:
Leaves Denmark... but the Queen of Denmark is the godmother of the new King. I that will be the reason for the King's visit.
Luxembourg: the Chef of the other Nassau-branch, a Benelux partner Germany: the neighbour in the East, the main trade partner Belgium: the neighbour in the South, a Benelux partner Denmark: the only godparent of the new King who is a ruling head of state
(The King's other godparents are/were: The late Prince Bernhard of the Netherlands The late Prince Aschwin zur Lippe-Biesterfeld Ferdinand Fürst von Bismarck Ms Thurlow Bradbrooke Smith née Jonkvrouw Elizabeth Röell.)
