All recent launches have had to have deorbit capability once the satellites have completed their mission. In Iridium's case, that means some fuel remaining is earmarked for the deorbiting. This is an international agreement but with various levels of participation by other governments. The problem usually is that if a satellite fails to function, it probably cannot be commanded to deorbit. The deorbit requirement would probably be mandatory in the case of Iridium because the system will be shut down. Leaving the satellites in that high an orbit, and without precise orbit trim maintenance, the satellites have a high probability of colliding with each other and the resulting debris clouds raining down on lower altitude satellites. The Iridium constellation, with its many satellites passing over the poles, is especially vulnerable to collision.
