Interesting view from this SLF type. Much ado about not much. reading linked AvH comments by several more less informed re NATO, violation of swiss airspace, etc seems to make even more doodoo . With the heightend tensions, etc, IMHO the old land at the planned airport in case of nordo probably no longer applies. To avoid possible baddies or confusion, the presence of a few fighter aircraft makes the desired /required flight path very clear including for sure avoiding other aircraft in a busy terminal area in a major population center.
