1. Surprise... The war does not take place over Syria - it takes place in Georgia, with a combined Turkish-Georgian assault on South Ossetia (yeah... Tskhinvali again. Don't ask how it comes about, just assume it does)
2. The war involves all of Turkish army, with 100,000 troops deployed in Georgia (with troop rotation) and the rest all over Turkey. It also includes several thousand anti-Russian volunteers from Ukraine, Poland, the Baltics and some Islamist militias.
3. No use of NBC weapons
4. Limitecd NATO support (intelligence data, armament)
5. The war should end with RUssian or, possibly, Greek troops in Istanbul.
Let your imagination get loose, guys.
