Are you kidding me?
This is an utterly meaningless and inane statement.
Provide some type of argument that has any valid form of legitimacy.

Yes, War does suck.  It sucks the big one, but often times it is necessary even when unpopular. 

Does this war we are in now suck?   Yes
But it is the required means to an end that we will face now, 10 years from now, 50 years from now, or we could have began to face 3-4 decades ago.
We chose to not pursue this course earlier because of political and societal misunderstanding of a complex rise and rebellion within differing socio-economic sects of the world that happened to be governed by differing sects of religions.  The ultimate outcome being unfostered hatred leading to the control of entire nations of people and provoking violence reminiscent of much earlier forms of society based largely on tribes and battling warlords. The difference now being the ability for the most uneducated of people to instill much larger numbers of casualties both physical and economic.

There is no easy or quick end in sight and there may very well never be a definitive end, but we must stabilize an area of the world that requires drastic change before there is any chance of creating a somewhat peaceful and free society which will foster this foresaid stability, and is the only chance we have of not beginning the long downfall that has become possible in a nuclear world.
