First, a definition from Ma Google's Wikipedia:
Every two years, preceding each edition of the Summer and Winter Olympic and Paralympic Games, the United Nations adopts a resolution calling for the observance of the Olympic Truce. This tradition harks back to the Games of Ancient Greece where, in the 9th century BC, the kings of the region would sign a treaty so that local inhabitants, athletes and artists could safely travel to the Olympic Games. According to custom, the ekecheira, or “truce” brought conflicts to a halt from seven days before the beginning of the Games until seven days after their conclusion.
In 2024, Russia and Belarus are banned from competion in the Summer Olympics in Paris. Athletes from those countries may enter as individuals but not as national representatives. There has been a call for Israel also to be prohibited from participation because of their ongoing bombardments of civilians in Gaza. Defenders of Israel point to Hamas as being the instigator of those attacks; however the Olympic Truce only asks for a cessation of hostilities for a period of seven days before and after the games. With 40,000 counted dead (and the liklihood of that number rising to 160,000 according to an article in The Lancet) the Palestinians are certainly not a belligerent within the terms of the UN Olympic Truce resolution for 2024.
Regarding Russia and Israel, only one of which has been denied entry in these Games, there is another commonality. The International Court of Justice and the International Criminal Court have rendered judgements. Russia and Israel are led by individuals accused of war crimes and those individuals are subject to arrest by "States Parties to the Rome Statute" of 1998. Notably absent from a list of those parties are the United States, Israel and China.
I had a look at definitions – I'm an English teacher; waddid ya expect. Here's a summary from the University of Melbourne, but the full reference is there also.
A TALE OF TWO COURTS IN ONE CITY
The ICJ and ICC are often confused with each other, and while both courts sit in The Hague, Netherlands, that is about where the similarities end.
The ICJ has been around since 1945 and its primary duty is to resolve disputes between States… Cases are brought by one State against another, in almost the same way that in a civil court, a plaintiff must sue a defendant to initiate proceedings. The difference is that at the ICJ proceedings can only be brought where both States have consented to the ICJ’s jurisdiction.
This consent can happen in a few different ways, but a common one is called a compromissory clause. There is one in the Genocide Convention
This means that where one State believes another to be committing genocide, if both States are parties to the Genocide Convention a case can be brought using this compromissory clause…. There are 153 State parties to the Genocide Convention, meaning that many States have the option of bringing a case against another State. Russia, Myanmar, and Israel are all parties to the Genocide Convention.
The ICC is a much more recent institution that has only been operating for about 20 years. Once States have ratified the Rome Statute, which sets out the list of crimes that the ICC can prosecute, they have almost no other role. … Usually, the Prosecutor will investigate a situation in which crimes have likely been committed such as in Darfur, Ukraine, Palestine, or Venezuela to name a few presently on the books.
If the Prosecutor’s team can gather enough evidence of crimes, link those crimes to individuals, and (this is the hardest part) have those people arrested, those individuals can be tried and convicted of a crime, and then imprisoned.
One of these crimes is genocide. The catch is that the Prosecutor is only permitted to open investigations into situations arising in countries that have ratified the Rome Statute. While the Rome Statute has 123 State parties, there are notable absentees including Russia, Israel, Myanmar and even the United States.
So, Israel is found guilty of genocide in its war in Gaza by the ICJ in a suit brought by South Africa. They (Israel) don't agree and aren't going to stop even though they are a member of the United Nations. Then, Netanyahu is convicted of war crimes by the ICC but since neither Israel not the US are parties to the Rome Statute, that means he can visit the States and not get arrested and turned over to the court at The Hague. And the Games, political and athletic, go on, with records being broken in both cases. For shame.
