There are three primary threads involved in Western containment of the Islamic Republic of Iran and preventing it from acquiring nuclear weapons capabilities: diplomacy, economic pressure and what the Israelis call “cutting the grass.”
Diplomacy can be harsh and can include economic pressure, as in the “maximum pressure campaign” of the outgoing administration, designed to cut off the mullahs’ funds in hopes of either collapsing the Tehran regime or forcing it to enter serious negotiations. It can also be soft, as in the Joint Comprehensive Plan of Action (JCPOA, or Iran nuclear deal) of the Obama administration, offering positive incentives in exchange for limitations or time constraints on threatening behaviors. “Cutting the grass”—reducing or eliminating actual military threats as they emerge in real time—has been Israel’s preferred method, and can be coupled with either of the two others.
“Maximum pressure” and “cutting the grass” have worked in tandem to severely constrain Iran. Hezbollah’s budget has been cut, Iran’s formerly 80,000-strong militia in Syria, commanded by Islamic Revolutionary Guard Corps (IRGC) officers, has been reduced to approximately 10,000, and the people of Iran have been protesting against their government. On the other hand, Iran has found ways to spend its limited funds on its priorities—namely, ballistic missile technology and nuclear weapons capability.
While the incoming Biden administration has made clear its preference for soft American diplomacy, a continuing alliance with Israel—public or tacit—that pressures Iran on the ground can serve both countries’ interests.
