With Turkey as the salient exception to the general rule, can you name one instance of an Islamic country getting along with a non-Muslim neighbor? Let alone even with fellow Muslim neighbors...
hmm, I beg to differ about Turkey. Armenian Genocide much? At the same time they exterminated several hundred Anatolian Greeks and Christian Assyrians too and many other Christians that were living in Turkey, which you dont hear much about. Jihad is jihad, its been going on for 1400 years, and is the "6th pillar of Islam".
their non-Muslim neighbours are Armenia and Greece. The border with Armenia is closed and they are only now trying to resurrect diplomatic relations (so they can project power into the Caucasus). And Greece is their mortal enemy - heard of Cyprus? where the Turkish population declared independence from Greece with help from the Turkish military.
The only reason Turkey seems moderate now is because the "father of all Turks" Ataturk, when he came to power after WW1, installed an ultra-secularist donctrine and put it upon the military to uphold it. He killed/jailed thousands of Imams and created the first instance of the separation of Mosque and State. Since then the army has been performing coups everytime a party with an Islamist agenda came to power (until this last lot - the army is losing its grip). Its illegal to bring religion into politics anyway, anyone who challenges their ultra-secular values in simply jailed or assassinated.
As for meddling, other then terrorizing their Kurdish population there is meddling aplenty in northern Iraq and they almost had a war with Syria, moving their troops to the border when the Syrians would not give up a KPP leader.
anyhow, they are now returning to their Ottoman Empire roots, beginning to project power again. And the more religious rural population has a far higher birth rate then the secular city dwellers, so Turkey will only revert further towards Islamism and away from secularism as time goes by, especially now that they wont become part of the EU.
