Why don't these people understand? The only way to defeat the ISIS is through a ground operation. Air strikes are useless against the ISIS, given the fact that they control hundreds of thousands of square kilometers of territory in both Syria and Iraq. If the French don't want to send in their army, then they can support the Kurds, who are currently waging a ground offensive against the ISIS.
France definitely wouldn't want to get into ground operations, especially after what happened to the US in Iraq and Afghanistan.
They have just taken the easy way out.
If I am not mistaken, they are already actively supporting the Kurds, through the supply of weapons.
