A discourse of this nature is not allowed in any Muslim majority country. As a whole, our political structures (be it secular or otherwise) are compromised by outside powers and interests to varying degrees. So, be it secular or an Islamic entity, the world's top powers will do their level best to prevent another competitor to rise.
In other words, any political discourse we have, it must reflect this reality as well, and any solution we propose, it must demand true unequivocal sovereignty for our countries. That's the only way we Muslims will be able to truly decide on our political, ideological, etc, etc framework, whatever that framework might be.
Otherwise, we'll see the status quo entities exploit popular sentiments (in any direction) to their benefit, and the cycle will continue. Today, folks will be suspicious of Islam, and then 50 years from now, we'll hate seculars, and back and forth we go without actually solving problems.
After WW2, China broke free of said shackles, and then it internally decided which course to take. We could have very well ended up with the ROC as our neighbour instead of the PRC, but in either scenario, it likely would have been an independent power.
