an example of when the UN did something right was when they pulled over 100,000 Iraqi soldiers from Kuwait in 1990 (When Iraq invaded Kuwait) thus achieving their aim of "keeping the peace"
an example of when the UN did something wrong was when they did not protect or try to stop the crisis in Darfur, numbers of the death during that civil war is still not perfected but estimated to be over 450,000, the UN did not classify this as a "genocide" so did not react only after 3 years, as stated by Mark Lattimer, "this level of crisis, the killings, rape and displacement could have been foreseen and avoided ... Darfur would just not be in this situation had the UN systems got its act together after Rwanda: their action was too little too late.
the UN also failed with regards to the invasion of Iraq in 2003, when they have yet to condemn America for their pre-emptive attack
hope that helps :)
