Ten years after the ICC was created, a new crime was added to those that the court will supposedly pursue: the crime of aggression. In other words, if a country or countries make war on another sovereign nation without the approval of the UN Security Council, those individuals who ordered the war can be charged. Even presidents and prime ministers.

The list of countries that have ratified the crime of aggression amendment to the Rome Statute isn't large. Countries that have signed, like Switzerland, are exactly the ones you wouldn't expect to see attacking another country. The countries that haven't ratified the amendment include Canada, the USA, the UK, France, Russia and China. Those countries refuse to allow their leaders to be held accountable for illegally attacking another nation.
