A balancing of power in the middle east is taking place. Each big country has to re-assess it's positions and chips in there.
Russia - It is currently busy with Ukraine, it lost almost all it's influence in the middle east (example Syria) and has a little with Iran. I would say, Iran is the last influence Russia had until they can resolve the Ukraine question
US - US thought they had influence until they hit the hard nail of Iran, I would say the recent US Iran war completely sober up the Americans and they really lost a lot of influence there at the moment. But knowing the old dog of US, they never give up and will come back again
China - China is spreading risk and it's chips around the middle east, not backing 1 side or the other, they back Iran when it needs to be back, or Saudi, or Pakistan. If one side weaken example Iran, or turns around, then the other chips Saudi/Pakistan will be increase. China will always have influence one way or the other
Saudi - Playing their cards quietly, they had recently change of bodyguard from US to the Pakistani.
Turkey - The old empire, still had the ambition, probably will be the new backer of whichever group, Muslim brotherhood. Recent gain in Syria has embolden them and even Lebanon group or Hezbollah may turn to them for support.
Pakistan - Big gains, the recent war with India really turn their fortune around. No more the old man beggars club, they got commissioned to be the new bodyguard of Saudis, more confident in their steps moving forward.
India - Seems to be the biggest loser or part of the loser group at this moment, so far, not one advantage out of the many recent events happening in the middle east. They resort to begging here and begging there. Even in the recent G7 meeting, Trump is no more hugging Modi like he used to be. The Indopacom command now changed back to Pacom, means the Indians getting sideline or found out to be not very useful to the Americans.
US - Another big loser, probably burns 30% of their cards/own national resources by initiating war with Iran and hittng nail with a bloody own toe. Causing their own bases/arrangement in the middle east to be targetted and wiped and breaking so many of their clientele trusts (Qatar/UAE, Saudi, Kuwait...etc) in the middle east and trusting the one conman Israel
Israel - I would say big winner so far. Even reputation/world condemnation, this mean nothing to them. The real control of the brain still the AIPAC/donor class in the US, they still control the country where it does matter at the moment. US. They still holding the land they gain from indisriminate AI bombing and killings. Just a few words of mouth condemning does not matter as long the land control gain is still there. Unless they lost those recent gain land, I would say Israel is a winner.
Iran- Iran oh Iran....schizo, they have 2 side, trying to appease the west and the other side. Split personality. I would not say, gain or lost....what they gain is also what they lost. They already lost their leaders and of course still there are hardliners, the appeasers still there, the traitors within still there. They fear they lost the influence of the other militant group like Houthis, Hezbollahs in Lebanon and others. These group may turn to other backers like Turkey, Saudi if they find their interest sold out by the appeasers in Iran to make that nonsense deal.
This is not end of the story for the middle east. There is Round 2 or Round 3 coming in.....everyone is now plotting and I'm sure the old dog Americans planning as well their next step. In Geopolitic unfortunately...you always look at the big picture to have clarify. Look at the big map from high above....all recent consideration, deals, ceasefire or whatever nonsense are just temporary...the wheels of geopolitic always move and push you into 1 direction. There is no permanent friends or enemies.......but permanent interests.......remember this lesson well to survive
