I'll put this here, because it's basically speculations, albeit by royal experts.
This is based on an interview of two, often used, royal experts in the (pretty trashy IMO) weekly Se & Hør.
It's Sebastian Olden-Jørgensen and Søren Jacobsen.
Both are royal commentators and authors of books about the DRF.
Now, I believe that royal experts when it comes to speculations are just as much experts as hardcore royal watchers on forums like this.
Having said that I post this, because this is AFAIK the first time serious royal experts have spoken strongly in favor of my pet-theory: That J&M are moving to France permanently.
I will translate their arguments without further comments from me.
Sebastian Olden-Jørgensen (SOJ):
Det ville ikke overraske mig, hvis prins Joachim og familien valgte at blive i udlandet, efter han har færdiggjort sin uddannelse.
Jeg synes egentlig, det er en klog beslutning, for jeg synes, den mand har nogle fiaskoer bag sig, og det her kan blive en ny start. Det er i hvert fald meget fornuftigt med et miljøskifte,
"It would not surprise me if Prince Joachim and the family chose to stay abroad after he has finished his education,
I actually think it's a wise decision, because I think that the man has some failures behind him and this can be a new start. It is in any way very prudent/sensible with a change of venue/scenery."
The two experts are not in agreement as to whether this will be a complete break with the DRF or not.
SOJ believes Joachim might very well do a Benedikte, while Søren Jacobsen (SO), believe he will leave for good also as a working member of the DRF.
Believes it is possible to live abroad while still remaining a working member of the DRF and mention Benedikte as an example of that.
Det hele afhænger jo af, hvordan han formår at varetage sine opgaver,
"It all depends on how he manages to carry out his tasks."
He adds that it might mean Joachim may have to give up some of his protections, but that other protections might benefit from that.
SO however, does not agree. He does not believe Joachim and Benedikte can be compared.
Hele det sønderjyske eventyr har sat en plet på Joachim, som Benedikte ikke har. Hun er Dronningens loyale søster, som stiller op, når hun skal,
"The whole Southern Jutlandic adventure has left a stain on Joachim, that Benedikte does not have. She is the Queen's loyal sister who stands in when she has to."
SO also believes it will be difficult for Joachim to look after his protections from France, but he does agree with SOJ that leaving for France will be a smart move by Joachim.
Man kan godt sammenligne forholdet mellem Kronprinsen og prins Joachim som situationen i en gammel adelsslægt, hvor der er to sønner: Den ene får godset (riget); den anden må finde anden beskæftigelse og helst i udlandet. Sådan blev en del af den gamle danske adel faktisk spredt ud i verden,
"You can well compare the relationship between the Crown Prince and Prince Joachim with the situation in an old noble family, where there are two sons: One gets the manor (the Realm); the other has to find another occupation and preferably abroad. That's actually the way a part of the old Danish nobility was spread all over the world."
SO and SOJ both agree that the move to France to attend the academy there is a step towards creating a life abroad.
Efter prins Henriks død så er Frankrig også frit på en måde, og derfor kan prins Joachim jo sætte sit præg på det – også uden at træde nogen over tæerne
"After the death of Prince Henrik, France is also sort of free and therefore Prince Joachim can put his mark on it - also without stepping on someone's toes."
France and surroundings that is. SOJ points to Paris or Brussels as alternatives and and explains why they would be better alternatives than returning to Denmark:
Det danske militær duer ikke rigtig. Uanset hvordan han klarer sin uddannelse, så vil det altid klæbe lidt ved jobbet, at det har han fået tildelt, fordi han er den, han er,
"The Danish military doesn't really work out (as an option). No matter how he copes in his education, there will always be the thought (in regards to a future job) that he has got it because he is who he is."
Now, since my opinion on this matter and my opinion as to why Joachim would leave DK for good has been made abundantly clear by now, I see no reason to repeat myself again and again.
I have therefore decided not to comment further for a while, unless there are news or as a response to a direct question.
I am much more interested in learning the opinions of our resident royal experts: You.
