Regime change is not a viable option to resolve Iranian nuclear crisis
Beyond the sheer challenge of trying to attempt regime change in Iran on a military and logistic level, there is the very real possibility that whatever regime taks the place of the one the U.S. topples will continue the nuclear weapons program for the very same reasons the current one is.
Quicktabs: Arguments
The regime-change thesis might seem more plausible if we had not heard similar arguments in the years leading up to the Iraq war. Indeed, the argument for regime change and the strategy embodied in the Iran Freedom Support Act are eerily reminiscent of the approach adopted with respect to Iraq between 1998 and 2003. Congress also passed and funded an Iraq Liberation Act during that period. American policymakers swallowed the self-serving propaganda of Ahmed Chalabi and the Iraqi National Congress, which said that with just modest U.S. financial and logistical support Iraqi factions opposed to Saddam Hussein would be able to overthrow his regime. It has since become apparent that the INC never had more than a meager domestic following. (Chalabi's party garnered less than 0.5 percent in the December 2005 parliamentary elections in Iraq.) There are manipulative (and in some cases utterly unsavory) Iranian exiles waiting in the wings to pull the same con game on Washington. They include notorious arms dealer Manucher Ghorbanifar, a shadowy figure in the Iran-Contra scandal during the Reagan administration. Perhaps the most unsavory opposition group is the Mujahideen-e-Khalq (MEK), which even the U.S. State Department considers a terrorist organization. The MEK , an organization founded on a combination of Islamism and Marxism, has a long history of terrorism and cult-like behavior. The MEK is the military wing of the National Council of Resistance of Iran (NCRI), regarded by many neoconservatives as a key ally in the effort to overthrow the Iranian clerical regime. After moving its base of operations from France to Iraq in 1986, the MEK was reportedly funded by Saddam Hussein's Baathist regime and sent into combat against Iran. It has also been implicated in the killing of American citizens. Currently led by a married couple, Masoud and Maryam Rajavi, the organization has increasingly become a cult of personality.
Third, would regime change in Iran alter its nuclear ambitions? Regime change could occur through the death or replacement of the Supreme Leader by a successor with less control over the IRGC or with a more pronounced taste for nuclear weapons, or election of reformminded leadership. In either case, however, most regional specialists anticipate no significant change in further development of nuclear weapons technology or compliance with the NPT and other international nonproliferation agreements.Support for the acquisition of advanced nuclear technology crosses ideological and factional lines. Iran scholars question whether Khamenei or his predecessor Ayatollah Khomeini approved Iran's possession and use of other weapons of mass destruction (chemical). They are uncertain, too, whether Khamenei has issued a fatwa sanctioning nuclear weapons or simply said they were un-Islamic.10 Reassessing the Implications of a Nuclear-Armed Iran Few believe that a more reformist-minded government would deny its right to take any measure it deemed necessary for national security. More broadly, press commentaries suggest Iranians increasingly resent foreign efforts to shape their policies on nuclear energy or deny them what is seen as a natural and national right. Considerations of regional prestige would also weigh upon the choices of any future government. If Iran were to step publicly over the nuclear threshold, it would trumpet its interest in sharing its new knowledge and technical advances with other Muslim countries. Even now, Iranian leaders speak publicly about sharing their technology and bringing the benefits of nuclearization to those less fortunate. Except for Israel, few foreign observers believe this means sharing nuclear weapons or other WMD assets with terrorist groups.
The reason a policy advocating regime change is a bad idea, given its potential benefits, is the fact that such a policy is beyond America's means. While the United States certainly possesses the capability to eliminate the regime in Tehran, as the invasion of Iraq has shown, eliminating the present leadership is the easy part of regime change. The more difficult and costly challenge is installing a new government. With America's resources already overly committed in Afghanistan and Iraq, taking on a new nation-building mission in a country far larger and in some ways far more nationalistic than Iraq would be the epitome of strategic overreach.
In theory, another military option exists: not drawing the line at an operation against nuclear sites in Iran, but carrying out a broad land-based assault aimed at overthrowing the Islamic regime in Tehran, as the United States did in Iraq and Afghanistan. Israel certainly does not have this option, even in theory; in practice, however, the US does not have it either. Iran's physical expanse, its terrain, and the size of its population and army make a military campaign to conquer the power centers in Iran far more complex and difficult than in Iraq and Afghanistan. After becoming entangled in Iraq, it is doubtful the US administration would embark on a similar operation in Iran. At the same time, if the administration decides on a military strike against nuclear sites in Iran, it cannot be ruled out that in addition to nuclear targets, it will hit other strategic sites. This option is also restricted to the US; it is difficult to believe that Israel would be willing or able to use it on any measurable scale.
Political Change: Roll back may come about as a result of a change in policy by the country's leadership, a change of governments, or as a result of regime change. It is possible that the current government in Tehran might abandon its nuclear ambitions in response to foreign pressure; indeed, some claim that the October 21st Agreement signals just such a change in course. Others, however, believe that this was a tactical move reminiscent of dramatic policy reversals by other regional leaders forced to bend by external pressures (e.g., Saddam Hussein during the Iran-Iraq War, Yassir Arafat after the 1991 Gulf War), that were undone once circumstances changed or external pressures abated. It remains to be seen whether Iran's current leadership will go beyond the October 21st Agreement. Initial signs are not very promising. Fundamental political change in Tehran may be a necessary condition for nuclear roll back in Iran. Such change seems inevitable, given that the overwhelming majority of Iranian youth are alienated from the political system, want change, and will someday likely be in a position to achieve it. It is not clear, however, that political change would be sufficient for roll back. To the degree that it is possible to assess elite and popular opinion in Iran on such matters, support for the country's nuclear program appears to come from across the political spectrum, and a new government or regime might remain wedded to the pursuit of 'the bomb.'

The authors counter the current Trump administration's call for regime change in Iran by referring to the historical record to show that regime change operations rarely work out the way the instigators intended.

"Just as they did with Saddam Hussein, concerned governments have implemented economic sanctions, diplomatic isolation, and low-level violence to weaken the Iranian regime and prevent it from acquiring nuclear weapons, with the long-term objective of regime change. In Iraq, and seemingly now in Iran, diplomacy and inspections became a means to an end: building up a casus belli. The strategy failed miserably in Iraq a decade ago. It probably will in Iran, too..."
