One interesting conclusion is that to have one sole mediator, and for that mediator to be the government of a small and not very powerful state rather than an international organisation or an NGO, was unsustainable. It would have been much better to have had a diverse team of involved actors who might have had more ability to cajole or even coerce the parties; it would have been much better if the government had not allowed itself to be both overstretched and undermined, the inevitable risks in the role of a single mediator. The government of Norway chose to put itself in this awkward position, and chose not to extricate itself sooner, and the report points out the alternatives available and the consequences which resulted from those choices.
Second, there were only two brief windows of opportunity for actually resolving the conflict during the Norwegians' mandate (in late 2001-early 2002, when a ceasefire was brokered, and in early 2005 immediately after the 26 December 2004 tsunami). On both occasions, the internal dynamics of the political situation allowed the situaton to slide back into violence, and while the report finds that the major responsibility for this lies with the parties, who were rarely negotiating in good faith and always negotiating at cross-purposes, still, a smarter and perhaps less modest mediation mission might not have let those opportunities slip.
As it was, the Norwegians remained impotently engaged well past the point when it was clear that a negotiated solution was impossible, and the report is clear that they should have terminated the mediation in 2006, thus making the extent of the crisis clear to the rest of the world, rather than hanging on until they were finally expelled in early 2009. There are words of praise for the individual and courageous efforts of the senior Norwegian officials involved and the Sri Lanka Monitoring Mission, but basically the report concludes that the mediation could have been done better, if indeed it was worth doing at all.
