I doubt that even makes sense to you, HOTYH.
I think you have chosen a position (R did not DI, therefore IDI) and you are trying to read everything in such a way as to defend R did not DI, IDI.
HOTYH, have you even read any books on this case?
The easiest thing for the perp to do, whatever their motive, would be this - once inside the house, they (one perp or the team of 2 or 3, as you suggest) bind, gag, and haul JBR out of the house. That's it. If there is any need to communicate to JR (about his business practices, "the country they serve" or anything else

) it could be handled by phone call.
"Hi JR, Listen carefully! We are a SFF and we have your daughter!..." etc.
A phone call at 5 AM is better than a RN - there would be no police trace on the phone, and they would be far away. If the perp was sooo rich, and spent sooo much money planning this, then subduing a 6 year old and gettign her out of the house and to a safe hideout would have been nothing. I could do it single handledly!!
Fact: " only about 6% of child murders are committed by strangers, while an overwhelming 54% are committed by family members." (the FBI, quoted in JonBenet:Inside the Ramsey Murder Investigation, ST)
Also from ST's book -
"I think it was someone with intimate knowledge of my family and how we lived day to day. Why would they leave the ransom note on the back stairway and not the front?" (JAR)
He (JAR) ridiculed the idea of a small foreign faction being involved, was certain the crime had nothing to do with his father's company, and questioned why a ransom note was left at all.
I ask again - did the Rs ever actually think a SFF was involved? or is HOTH the only person on the planet who thinks the SFFDI?
