"Even after its was realized that there was a diplomatic option..." If the "diplomatic options" would have worked, we probably wouldn't be fighting a war now... If there is other options that will work, what are they?? How do you negotiate with people whose sole mission is to see you dead?? "Don't try to kill us today...Perhaps in few years..." They want to wipe us off the map (yes, they still do, that hasn't changed in the past 60 years) we have to be stronger than they are. "In the war now, military force is the be all and end all. Perhaps, its failure to attain its goals will lead to rethinking the use of the army as the solution to every problem..." Perhaps you should wait until the operation is a failure before calling it a failure.
