If 1400 year of islam history teach us anything, is that muslims are relentless. They can never stop, and will not stop, until the whole world is under the muslim sword. House of Peace and House of War. Dar al Islam and Dar al Harb. The land they conquered, and the land they plan to conquer.
Muslims will stop advancing only in one instance: when the odds are overwhelmingly against them. Even then, they'll try to threaten and get some material advantage out of it, in form of tribute / tax. In the meantime, they'll send their spies to infiltrate the enemy, scout for the weak spots, buying off leaders in the army and in politics. Sound familiar? Buying for themselves the George Galloways of the Middle Ages. Today, brazenly requesting pallets of cash so they slowdown their weapon development, in a situation when they could be obliterated in less than 24h
And is not only Iran, the rich Gulf States are doing the same - playing friendly, buying weapons with their seemingly unlimited reserves of paper while on the back door they're funneling support to the most vicious jihadi groups. They have the left in their pocket, and globalists like Bandar Bush too. Weapons depots mosques are sprawling all over the Western world, safe spaces for propaganda and recruitment centers.
They will never stop. With the plot twists that today, half of their intended targets are supporting them.
Thing is, Iran never properly converted to islam. They're seen as dirty dogs no better than kuffars by the sunnis, because many do not follow islam literally. They do not have the amount of inbreeding Arabs have, hence they're able to maintain a relative technological capabilities (compared with the Gulf States who are genuine retards). If there is a country in history able to revert islam since Reconquista, then is Iranian urban population.
However, I think is the 10th time people went to the streets in Iran only to be mowed down by the militias. They have no chance without their Army turning their guns on Basij and Quds forces, and they're not capable to do it even if willing. 3/4 of the population turning away from islam, and there would still be 20 million religious fanatics to hunt them down.
Tough situation.
