The Islamic Republic’s pursuit of nuclear weapons and long-range ballistic missiles is not a bargaining chip. It is an ideological imperative. The theocratic system that has ruled Iran since 1979 treats the acquisition of these capabilities as a religious and revolutionary duty, not a negotiable national interest. U.S. sanctions, diplomacy, and limited strikes have repeatedly demonstrated the same pattern: temporary Iranian setbacks followed by reconstitution. As long as the regime’s core ideology and coercive apparatus remain intact, the nuclear and missile programs will continue. Regime change is therefore not optional theater. It is the only durable way to remove the ideological driver itself.
