Knowing the law and upholding the law are not necessarily the same thing though.
Britains Labour party leader Keir Starmer is also a lawyer specialised in international human rights, yet he repeatedly claimed Israeli war crimes not to be war crimes.
Germany currently has a scandal, where the ministry of education tried to defund researchers who signed an open letter, defending students rights to protest. First of all this is highly unconstitutional and unethical, because the constitution grants both freedome of speech and freedom of science. Second of all, targeting dissident scientists is particularly icky in Germany, given the Nazi history. The executor of that ministers order, who was then sacrificed to take the whole blame for it, was the head of Germanys ethics advisor council to the government.
Both the escalation on the southern Lebanon border and the resulting displacement have received a lot of media coverage. Hezbollah has kept saying that this is to keep IDF from being all focused on Gaza and that they would stop if a ceasefire is reached. Until about three month ago both Israel and Hezbollah have been trying to keep the level of escalation low.
This has changes as Israel attacked Beirut and threatened to turn it into "another Gaza" and boasting about how they could destroy all of Lebanon. Netanyahus government has aimed to escalate the war there, to draw in the US and other western allies.
Now whether we will see the full escalation now remains to be seen. Hezbollah is a whole different league compared to Hamas in terms of weapons and fighters.
