France has a deep history and Macron doesn't want to do anything except raise the defense budget, because that's the best way to avoid problems: condemn violence but don't participate and stay alert.
"international law" is, i don't know how to say this quite right, largely for show
when both sides seem to be willing and eager to order, participate in, and cheer for atrocities from leadership to the common people... I don't want to take ideological sides or tally up crimes to decide who to root for in millennia old conflict mostly over a single city
it's a terrible shame for the people who want to live together in peace, clearly there are not enough of them
Yes, there's an ICC warrant out by for Netanyahu and Gallant.
Basically that just means that they won't travel to or even be invited to countries that would arrest them.
The same goes for Putin.
A lot of pro-Israel people just think the ICC is just a tool used by countries that hold a grudge against Israel and don't take it seriously (e.g. the Biden administration released a statement condemning the ICC when they announced they were seeking the warrants), so having more first-hand witnesses stating clearly that war crimes are happening is relevant.
Ideally we'd have journalists reporting these things, but Israel blocks those from entering Gaza too.
I expect the warrant against Putin will be the same ignored as a warrant against Netanyahu. Both Russia and Israel have certain bribing and soft power, but even ignored as a revenge. e.g. Polish prime minister and president jointly and proactively guaranteed Netanyahu entry to Poland even if on daily basis they belong to opposing parties which hate each other. A gesture which looks outright suicidal considering the Criminal Court and local geopolitics.
The hypocrisy is stunning.
