Nuclear Iran would help stabilize Middle East
Quicktabs: Arguments
Third, Israel has made clear that it feels threatened by Iran’s nuclear program. The Palestinians also have a reason for concern, because a nuclear strike against Israel would devastate them as well. This shared danger might serve as a catalyst for reconciliation between the two parties, leading to the peace agreement that has eluded the last five presidents. Paradoxically, any final agreement between Israelis and Palestinians would go a long way to undercutting Tehran’s animosity toward Israel, and would ease longstanding tensions in the region.
Limiting Israeli freedom of action. Israeli strategic culture places a high value on the ability to conduct retaliatory strikes for attacks against Israeli citi- zens, as well as to take preemptive action to prevent certain arms transfers that cross Israeli red lines. Already, the threat of escalating conflict has forced Israel to accept the transfer of certain precision- guided missiles, antiaircraft systems, and, report- edly, Scud ballistic missiles.81 But in the face of a nuclear-capable Iran, Israel might be forced to act with even greater caution in initiating preemptive or retaliatory strikes—given the potential of these strikes to escalate into a direct conflict with Iran.82 As a result, Hizballah and Hamas may feel more free to engage in low-level military actions against Israeli civilians, potentially including more frequent rocket attacks, targeted assassinations, or suicide bombings. Furthermore, an Iranian nuclear capabil- ity could induce Tehran or Syria to transfer increas- ing numbers of sophisticated weapons to Hizbal- lah or Hamas. A particularly dangerous escalation could involve the potential transfer to Hizballah of radiological dispersion devices (or “dirty bombs”) or even chemical weapons. While attempting such transfers would be provocative, Tehran might cal- culate that the psychological impact on the Israeli population and the deterrent effect on the Israeli military would be significant enough to warrant such risks.
First, Iran’s development of nuclear weapons would give the United States an opportunity to finally defeat violent Sunni-Arab terrorist groups like Al Qaeda. Here’s why: a nuclear Iran is primarily a threat to its neighbors, not the United States. Thus Washington could offer regional security — primarily, a Middle East nuclear umbrella — in exchange for economic, political and social reforms in the autocratic Arab regimes responsible for breeding the discontent that led to the attacks of Sept. 11, 2001. Until now, the Middle East autocracies have refused to change their ways because they were protected by the wealth of their petroleum reserves. A nuclear Iran alters the regional dynamic significantly, and provides some leverage for us to demand reforms.

The author, a defense analyst at the Air Force Research Institute, argues that the U.S. could reap a few security benefits from the new Middle East order that would result from Iranian nuclear proliferation.
