but I am wondering if all this drama maybe more simply due to Harry being extremely fixated about the safety issue as opposed to being purely about the drama/pressuring Ravec
If you mean that Harry has genuine fears about his and his family's security, then no.
Look at all the evidence to the contrary.
Moving to Britain seemingly on a whim, without making adequate security arrangements.
His wife constantly posting photos of the children in private locations which are easily identifiable.
Him and his wife leaving their children for days or even weeks at a time. Sometimes to travel to another continent.
Them announcing their movements in advance.
Harry going around ringing doorbells in London.
And probably lots more that I can't think of right now. But there is plenty of evidence that neither of them is terribly concerned about security itself, rather about the status they believe official security provides.
