We like to think we're winning, but are we ? Iran leadership is supposedly decimated, missile capabilities destroyed etc. And yet, when Israel attacked their gas field, they immediately wiped out 17% of Qatari gas productions capacities which will take 5 years to rebuild and they could have wiped out everything. Seems their leadership structure is doing just fine.
As for all the killed - what did we actually achieve ? Replace Khamenei with his son - a guy who had all of his family blown up to pieces by US / Israeli ? That should do wonders to Iran's future relationship with those countries.
