When the images of dead kids are posted all over the net?

The last time that kind of thing happened it looked like this. tl;dr: It's better to come clean proactively because ultimately the Bundeswehr leaks like a sieve in these kinds of matters, which is a good thing.

The question for the public at large will be "is this cleaner than the IDF doing things" and the answer is invariably yes: Even if the IDF was a troop of angels there's a fuckton of baggage making it impossible for Gazans to see them as protectors.

Or when Netanyahu slips in a couple of hundred armed settlers?

None of this will happen with Netanyahu and his fascists still in power. I believe that's the third time I'm saying that now.

Plenty of Israelis went into Gaza all the time without any issues, btw. Figures that Palestinians can tell Smolanim and Kahanites apart.

Will the Germans evict those Jews by force? Will that event be in the German National Interest?

That's a police matter. Palestine has every right in the world to deport illegal immigrants.
