Missile defence has become increasingly attractive in recent years, following the demonstration of its efficacity in the Israeli-Iranian conflict, and has epitomised by the ambitious Golden Dome programme. However, its relationship with missile proliferation is ambiguous. Arms control, non-proliferation and confidence building measures can to some extent address some of the most destabilizing features of this offense-defence competition.

After listing major programmes and key drivers beyond the acquisition of these technologies, this paper considers their development under the prism of arms control, and analyses whether current mechanisms (non-proliferation arrangements, bilateral arms control treaties and confidence-building measures) dealing with missiles are adapted to these weapons.
