Airstrikes alone will not stop Iran, but the missing phase is not a ground invasion. It is to starve the regime of money.
The United States should not offer or accept any partial deal to or from the IRGC (Iran Revolutionary Guards Corps).
The next phase in the Iran campaign must be one of financial compellence - forcing Iran to do the right thing before it collapses.
If Iran refuses to deal, the United States could strike Kharg Island militarily and apply new financial weapons against the "shadow fleet."
