The report produced by my commission, the Global Commission on Elections, Democracy and Security, in 2012 showed the corrosive impact of money in US politics, for example, which undermines the legitimacy of the democratic system in citizens' eyes. Such perceptions partly explain the rise of a phenomenon like the success of Donald Trump.

Obama saying Gaddafi must go. Putting it upfront like that... it's not very helpful.

UN peacekeeping operations are now increasingly complex and multi-dimensional, going beyond monitoring a ceasefire to actually bringing failed States back to life, often after decades of conflict. The blue helmets and their civilian colleagues work together to organize elections, enact police and judicial reform, promote and protect human rights, conduct mine-clearance, advance gender equality, achieve the voluntary disarmament of former combatants, and support the return of refugees and displaced people to their homes.

A world government can intervene militarily in the internal affairs of any nation when it disapproves of their activities.

Sadly, a prize for peace is a rarity in this world. Most nations have monuments or memorials to war, bronze salutations to heroic battles, archways of triumph. But peace has no parade, no pantheon of victory.

The [UN Security Council] P5 ought to be dissuaded from using their veto power, which can paralyze the United Nations. The country blocking action ought to have to explain its decision and propose an alternative solution. It has been suggested that a veto only becomes effective if the vetoing state has the support of two or three other permanent members.

International law now grants rights to all human beings, not only to citizens.
