A little bit of brainstorming on my part:
I think that Iran should go for a ceasefire that maintains the status quo. Don’t make any concessions to the Baal worshippers and expect none. Accept a ceasefire like after the 12-day war.
The above will mean that the war is not over and can restart again. That’s correct, and Iran should spend the intervening time to prepare for the next round.
What is clear is that neither Iran nor any other country in the Middle East, or any Muslim country can expect to live in peace as long as Israel exists supported by the US. It should become an openly declared objective of all Muslims to get rid of Israel.
It is also clear that the US-Israel backed puppet regimes are a threat to not just Iran but to all the Muslims of the region. It should become an openly declared aim to get rid of all of them and replace them with representative governments.
Iran’s weakness that prevents it from becoming the de facto leader of all 2 billion Muslims is the sectarian issue. It’s unfortunate but true. The best way to overcome it is to partner with a major Sunni power like Turkey if old animosities or rivalries can be overcome. However, Iran can also tap into the ‘International Muslim’ which consists of hundreds of millions of mostly young online Muslims who support Iran.
Between the end of this war and the start of the next one, there might be a few years. In that time Iran would need to strengthen itself militarily and work on uniting the Muslim world to create an alliance.
My prediction is that the next round will the final one, maybe 10-100 times more destructive than this one. It will be the whole (or most of the) Muslim world against the Zionist controlled West. It will be the final and decisive battle.
In short, stop this war and prepare for the final one.
