This is the logic behind the old-style Jihad. Also the Chinese emperors used the same argument when conquering smaller kingdoms.

Unfortunately, what happens in practice is that even in one Islamic country Sunni vs Shia terrorists attacks happen. And in the case of China, the price you pay for superficial peace are Uighur concentration camps, Tibetan self-immolations and so on.
