So, if Muslims were powerful enough, they would have tried to solve with dialogue and economic pressure oppression of Muslims or Non-Muslims in China, India, Myanamar, Syria, Yemen, and other countries.
If after reasonable effort, the oppression was not stopped, the Muslim government would have tried to replace the government there through supporting the other parties and awakening the people of the country to replace the government (Revolution from within).
If that would not have worked, put economic sanctions to weaken the government and to turn people against the government. Then help instigate a coup with the help of special units and replace the government (Mild Force).
If that would have not worked, attack the country and replace the government, established its military bases there (soft take over) to keep new government in check.
If that was not feasible, attack the country, establish a favorable government and make the country its colony.
In extreme case, where Muslim government was very powerful, they would have taken over the country and assimilate in its own national boundaries.
All this the same as what the West is doing mostly for economic reasons, to keep rival religion in check and to keep rival countries from not getting too strong to create problem from them.
