For America they have to be vigilant of Israel's actions in the region for possible Sabotage, some people just can't help it when they are motivated by End time prophecies and waiting for some Messiah to come make them King and everyone else their slaves, its a promise too good to be ignored even if it means slaughtering 20-30k innocent children.
I like that Iran has mentioned Lebanon in every press release and they haven't abandoned Lebanon, and I hope that Iran will not compromise on Lebanon's lost territory either, Hezbullah new found tactics with Drones if used more effectively can panic Israel's, they have a lot of bombs and Air superiority but what they don't have is manpower to spare, if this war is over we will see more suicides in IDF due to PTSD.
Pakistan, i really hope that we fix our internal issues, and we manage to finish the Iran-Pakistan Gas pipeline which will help a lot, I don't Trust Indian filth one bit but they could've benefitted a lot with the continuation of same pipeline into Iran and even branch off into Afghanistan-Central Asia, but unfortunately we are dealing with Galeez nation on 2 fronts Afghans/Indians who will not let the region thrive and have peace.
Pakistan needs to sit and have serious talks with KSA/Qatar about the security Agreement, you want 2 sq's and 80k troops with proper AD and logistics you gotta pay up, we have our own internal/external conflicts to take, so we can't spare the money which we don't even have for KSA/Qatar protection from Israel. I hope Qatar announce a similar deal soon, and start funneling some money into Pakistani defense forces, given the new Rocket Command we can put some serious fire power on the door steps of Israel, I wish to be wrong but Turkey is basically useless, i thought highly of them but they turn out that their old leader and some minister will issue cringy statements against Israel while doing business with them providing them with oil and money.
As for Iran, I think if the peace holds, needless to say they will be building more missile cities, mass producing drones, and even lots of stuff from US they shoot down and those which remain in somewhat decent condition will be studied and re-engineered into Iranian versions. I hope that Iran focus on its Air force, with some good BVR capability, and long range low flying munitions for any further Israel's aggression.
I hope Gaza rebuilding process can resume and hasten, so in Lebanon. I knows its a fool's dream but Israel can become the catalyst of peace if they recognize a unarmed Palestinian state who's security is guaranteed by Peace keeping forces, and with Palestinians who are supported by Arabs/Iran and Israel who is darling of west, both nations can co-exists and finally ends to much of the mess within the region, as for power struggle between Shia/Sunni blocks will remain, civil wars will still happen in ME, but at least that one hot point of many wars/conflicts can finally be put to rest only if Israel accept peace, which like i said is unlikely.
