It must be inevitable, given most of the other countries with predominantly Muslim populations have already had their backs broken by the US and it's lapdogs.
Turkey seems to have served it's usefulness to the US and is almost redundant now.
How long to go? clearly it can't happen overnight as that country is militarily pretty powerful so will need to be broken from the inside like the others in the region.
Internal conflict, agent provocateurs, false flag operations etc etc all incoming within the next 3 years I reckon.
