Yes. 200 km is a very large distance. Especially in the Sahara desert where there are no roads or even isolated tracks. Even the Egyptian military uses helicopters to get its personal to the Bir Tawil. How do you expect the pirates to get there. Also, given the naval patrols being conducted by the navies of Egypt and Saudi Arabia in the Red sea, I don't find it possible for the Somali pirates to reach anywhere near that area.
