Since when is murder, massmurder, rapes, torture, bombardements to legitimate?

The US acts against international law: officially.

You claim nothing else than that the NATO would fight a clean war.

I suppose you do not know the airforce doctrine document by General Warden.
It is official: Battlefield of the Future

His ring system shows the main targets by the airforce:
1) Leadership
2) System Essentials
3) Infrastructure
4) Population
5) Fielded Military

He says also: "Contrary to Clausewitz, destruction of the enemy military is not the essence of war; the essence of war is convincing the enemy to accept your position, and fighting his military forces is at best a means to an end and at worst a total waste of time and energy."

This document is in force until today. So what is the main aim now? The bombings of civilians are often called "accidents". In fact it is the strategy. To bomb the population as long until they give up.

No, the US government considers Iran as its biggest enemy and the Iranian regime considers the US as its biggest enemy. So there's at least one point where both countries are in complete agreement.
That's so funny with your "enemies". As the US helped the Shah to gain the power and to install a regime in Iran, Iran was the US's "pearl". If Iran is now what it is today, then because of Western interferences.

lol
There isn't even the half of people they show in TV, cause the cameras zooms in and it looks like if there would be millions. Ever seen such protests in overview? No? This has its reasons, cause the shock effect would get lost.
Do you know why there counterdemonstrations? Would you demonstrate if you're living in a dictatorship? So it is ridiculous if Westerners desire from Muslims to demonstrate against Islamists, cause they simply can't. I would laugh if I'd live in a dictatorship and someone at world's end would desire from me to show that I'm not against this other world's end.
Do you know that these "demonstrations" are often staged by the regimes and people from the intelligence services take part often in these demonstrations? Do you know why the regimes do that stage? Cause they want to show that it would be much better if Western governments would negotiate with them than overthrow them.

Do you mean in 1979? I hope the people know a bit more about Iran's history than the occupation of the American embassy. That the Islamic revolution happened, has its (Western) causes...

Or let's say it as Western governments wants to show us: The West is good, shiny, wonderful, peaceful, rich, helpful...
ME is: bad because the are living muslims and all of them are islamists (we just trained Bin Laden), violates human rights (but we just back that), is poor (because we hold down their markets), hates the West (because Western reporters film staged demonstrations) and is all in all boring (because we do not know their culture, their history but judge over their people's mentality).

The Nato does, even if it is not necessary to act that brutal.

I hope ALL here know, that this said France, Germany and GB in WW1 (something like : "we're fighting militarism and imperialism and in the name of peace"), I hope ALL here know that Hitler said he wants peace, that in fact all war mongers said they want peace, but made war.
So why is there war if everybody wants peace?

You do not make war in the name of peace. It's disgusting if governments are claiming that.
Militarism is fighting for peace...? Would be new to me! Yes, it is the holy thing of human rights, peace and freedom and democraZy, that makes us crusaders and every other person who does not share this view is a traitor, crazy or paranoid.

That's up to you. I would consider that the West is much better to its own people than anywhere else, but I certainly wouldn't consider that the West is much better to people who live in other regions and have to suffer under regimes.
