Wesley Clark was part of the operation to separate (Muslim) Kosovo from Serbia. One can hardly expect him to say Islam is bad.
The Serbia war operation was worse than a mistake. But Clark is correct about ISIS in Syria. The West created it through their proxies Qatar, Turkey and Saudi Arabia. Moreover, Syria is a secular state. Bashar Assad is a secular Alawite married to a Sunni. He speaks four languages fluently and is a medical doctor. That’s why the West wants to vilify him and get rid of him – they’re jealous of his intelligence and decency.
