Publishing a book about a highly charged ethnic conflict in which tens of thousands have died is no path to a peaceful life. You only need to look at the racial abuse and filthy language in the comments sections of online sites frequented by Sri Lankans to see how intense the emotions still are.

It's been frustrating to watch the international reporting of the story of the impeachment of Sri Lanka's top judge. Some reports have got bogged down in the issue of whether or not she is guilty of corruption. That's not the issue at stake.

The Sri Lankan military is advertising a newly constructed hotel in the heart of the killing fields in the north of the island, where tens of thousands of minority Tamils were killed in 2009. Right in the heart of what was rebel territory, the hotel overlooks the stretch of water that became the frontline during the final bloody months of the conflict.

If today the United Nations announced that it had received unconfirmed reports of 50,000 casualties in a war off limits to journalists - wouldn't the world take notice and try and stop the killings? We now know the UN system had this information in 2009 about Sri Lanka and suppressed it. We know this because of an internal review, commissioned by the UN Secretary General, Ban ki Moon. It's a report that concludes that the UN's conduct at the end of the civil war in Sri Lanka marked a "grave failure" that "should not happen again".

I was very privileged to attend Aung San Suu Kyi's historic speech to both Houses of Parliament in Westminster Hall last week.

In the north east of Sri Lanka just now there is a brutal and repressive clamp-down on the Tamil population. Thousands are still homeless while the military has seized land and homes. Around the world a generation of Tamil youth are burning with anger. If the world does not take action to find the truth and make the perpetrators face justice, that anger may find its expression in a tragic, awful, repetition of history.
