No one except for al-Assad's army is fighting against ISIS or other terrorist organisations in Syria, no one else is fighting them on Syrian territory. Minor airstrikes, including those by the United States aircraft, do not resolve the issue in essence; in fact, they do not resolve it at all.
Gaze not on beauty too much, lest it blast thee; nor too long, lest it blind thee; nor too near, lest it burn thee. If thou like it, it deceives thee; if thou love it, it disturbs thee; if thou hunt after it, it destroys thee. If virtue accompany it, it is the heart's paradise; if vice associate it, it is the soul's purgatory. It is the wise man's bonfire, and the fool's furnace.
