You haven't really made an argument of your own. You've just made a claim and presented no evidence. "Simple as that" is neither argument nor evidence nor rationale. This is no better than the people who fall back on "war is hell" to justify when they've fucked up and caused the deaths and suffering of a bunch of civilians for no good purpose.

You could at least say something like "we have to bomb the people so they can be free" or "don't you know the Iranians were seconds away from nuking new York, because they have no regard for their own survival".

We should "deprecate" offensive wars of choice based on lies because the opportunity cost is enormous (what could we have bought with the 200+ billion they're already looking to spend here?).

Every time we do this we create more terrorists (see the blowback incidents weve already had from this war), which results in more egregious government overreach on the domestic population (see patriot act and the experience of commercial flight in today's world).

And those are just some of the basic reasons. I don't have time to write them all.
