Where is the UN?

How come UN and other foreign countries are not able to stop the war in Sri Lanka?
There are thousands of protesters all over the world demanding cease fire, political solution, and to stop the killing of the innocent Tamils.

Why is the UN so blind to see the sufferings of the Tamil people in the war zone. If the Sri Lankan government cares about the Tamils how come they started this war by breaking cease fire???
Now they claim that they are doing a great humanitarian rescue operation to save Tamil.

But lets review some facts.

First the government breaks the cause not willing to solve this problem politically. They knew that almost every will vote for self determination. So as long there is a cease fire they can't prevent this peaceful solution.
They started to sabotage the cease fire and finally started a major offensive killing thousands of Tamil civilians.
They ordered all foreign NGO's to leave the north to hide their war crimes against Tamil Civilians.
They used illegal weapons including cluster bombs on Civilians.
The whole think about LTTE using people as human shields is another propaganda of the Sri Lankan government. If the LTTE was using people as humans shields, how can the army advance and take control all most entire area controlled by the LTTE.
Not allowing free media to the war zone is another dirty way to hide their killings.
The people who went to the gov area is not to seek protection with them. But they  went because they have seem thousands of dead bodies caused by shells and bombs the army is using on civilians.

They went to the gov area to escape the bombs. But these people are put in concentration camps behind barbwire. Many went to these camps are killed and many disappeared. The government call this saving the Tamils.
Many thousands of people including babies, kids, women and many young Tamils are victims of this failed racist Sri Lankan government and its ruthless Army.

In what way it is justified that people in power can decide other ppl lives without knowing the real situation. How many of the Sri Lankan officials went to vanni and heard the burdens of the Tamils there? How can the world just watch thousands of ppl being killed every day?

I ve seen many horrible images in the last months. But there is one image still disturbing me. A boy ( I think 3 years old ) lying in a field ripped apart by a bomb. I hope that his parents died along with him. I don't think that they can bare the lost of their child this way.
