No- not every Muslim nation- but still, Syria, Yemen, Libya, Iraq, Afghanistan, Mali, Somalia, Nigeria (not 90%) are in full out conflicts. Turkey, Egypt, Pakistan, Tunisia, Lebanon (not 90% Muslim) but in the region, suffer from lower grade insurgencies and endemic terrorism. Most of the Gulf states are close to civil war as Sunni Princes attempt to suppress their mostly Shia populations with the help of Wahhabi Saudi Arabia. Corrupt rulers in Malaysia are enlisting the aide of Muslim extremists in maintaining control in that endangered democracy as do rulers in Indonesia do all too often. Much of the Wahhabi vomit is promoted funded by the Saudis as extremist Shia militias in the region are supported by Iran. All in all it is not a pretty picture.
