Donald Trump is rightfully turning up the pressure against Iran by gradually removing exceptions to the sanctions. However, some supporters of this measure are possibly overstating the potential that the misery created by such sanctions will finally provide the Iranian people with enough motivation to overthrow their regime. One thing that events of this year should teach us is that the Iranian people have no shortage of motivation to overthrow their regime. What they lack is capacity, which no amount of sanctions can provide.
In the linked example, insurgents in Sistan-Baluchistan attacked an IRGC personnel carrier. The only tear we should shed over the fallen IRGC members is that the casualty number didn't have a few zeros appended at the right. However, we should not pretend that the loss of a few dozen grunts, or even a couple thousand grunts, would actually degrade the IRGC's ability to repress the Iranian people. What's needed is to build the Baluchi Army of Justice, Jaish ul Adl, and the Arab Struggle Movement for the Liberation of Ahvaz into a force that can be to the IRGC what the Houthis are to the legitimate government of Yemen. In order to become such a threat, those organizations would need two things. First is the strategic acumen to identify consequential targets, that is targets whose being hit would meaningfully degrade the regime's ability to cement its hold on power. The second is the tactical ability to hit those targets.
The first of those could be achieved by bringing the insurgent leaders to a safe destination where either American or Israeli operatives could train them. The second might also require the delivery of materiel, but if Israel can smuggle the nuclear archive out of Tehran, Israel can smuggle armaments to the insurgents.
