Eight weeks into the Iran war, the regime is seriously fractured. Power is divided, internal factions are competing, and the pressure from economic and military constraints is beginning to take its toll.

With sanctions, blockades, and internal instability mounting, the question is no longer if Iran is weakening, but how long it can hold together before an inevitable collapse. 

As the situation develops, decisions made now could determine whether this conflict ends decisively or drags on, argues Victor Davis Hanson.
