Key development: Israel opened a new phase of the war — targeting the Iranian regime's industrial and nuclear infrastructure. The Israeli Air Force bombed the Arak heavy water reactor (Khondab), the Ardakan yellowcake facility, the central naval missile and sea mine production center in Yazd, and two major IRGC-owned steel plants (Khuzestan Steel and Mobarakeh Steel). Simultaneously, dozens of weapons production sites in Tehran were struck overnight.
Trump extended the deadline for strikes on the Iranian regime's energy infrastructure by 10 days (to April 6), claiming "talks are going very well." Rubio told the G7 in France that operations will conclude in "weeks, not months." However, VP Vance reportedly chided Netanyahu for overselling the chances of regime change — signaling a Washington-Tel Aviv split on war endgame.
The IRGC declared the Strait of Hormuz "closed" and turned back three ships including two Chinese COSCO vessels — enforcing restrictions even on non-Western partners. The Iranian regime submitted a counter-proposal to the US 15-point plan via Pakistan but showed no signs of backing down.
Distance to collapse threshold: 9.5 points. The expansion of strikes to economic infrastructure (steel) and nuclear targets (Arak + Ardakan) marks a new phase of systematic regime erosion.

The Regime Death Index rose from 55.1% (Day 27) to 55.5% (Day 28). Distance to collapse threshold: 9.5 points. Three key factors today:
First: Expansion of strikes to industrial infrastructure — bombing two major IRGC-owned steel plants is a direct blow to the Iranian regime's economic pillar. The IRGC controls a major portion of Iran's economy through subsidiary companies, and attacking these facilities targets the financial resources sustaining the war.
Second: Destruction of the Yazd naval missile and sea mine production center — following Tangsiri's elimination yesterday, destroying the naval weapons production infrastructure is a structural blow to Hormuz blockade capability. The Iranian regime still holds the strait closed but its ability to reproduce maritime weapons is effectively eliminated.
Third: Renewed strikes on the Arak reactor and Ardakan yellowcake facility — Israel sends a clear message: no nuclear reconstruction will be tolerated. Cutting the nuclear supply chain (from uranium extraction to plutonium production) is one of the war's endgame objectives.
Watch point: The energy deadline extension to April 6 creates a 10-day diplomatic window. If it closes without results, strikes on energy infrastructure could push RDI up 3-5 points and bring the distance to the 65% threshold below 5 points. The Vance-Netanyahu split on regime change is also a significant uncertainty factor.
