Alexander the Great reportedly stated :-
"I would rather face an army of Lions commanded by a Sheep than an army of Sheep commanded by a Lion !".
It would appear that the 'Lionhearted' leadership of IS regard the forces of the West as rather 'Sheepish' in their lack of enthusiasm to engage in a fair fight ?, nothing new there, the murderous onslaughts (which we ALL have witnessed over the past years) of those Western forces whose only REAL justification for such onslaughts is to steal the resources of the nations they attack or depose the leadership of nations which refuse to cower to their bullying, NOW face a force of resistance which they did not anticipate and will never defeat by 'Force of Arms'.
SHAME is the only reward for the actions of the West in recent years, the unrest which now spreads in so many nations is the direct result of 'Western Aggression' (in many disguises) and there are those who would rather die than capitulate to such veiled aggression.
How sad that those who resist are forced to resort to such horrific acts of retaliation, in all probability a considered ploy to encourage the 'Savages of the West' to think about the evils they have perpetrated and the reactions they have (unexpectedly) encouraged from those oppose their campaigns of terror.
