It's tactical.
Governments are puppets of the persons who are responsible for the international arms trade.
Israel is a very important country due to arms trade.
The court in The Hague is maybe acussing Israel of some genocide; however. When clearly USA & UK are joining, on a kinda visible side-part, the war;
The Hague can say Israel is guilty but when it is so clearly they are backed by the USA/UK/EU such judgment is as weak as a kitten.
So, very tactical.
And don't forget; the (our) governments are seemingly run by our leaders but these so called leaders receive orders as well.
It's all one big facade.
