Since when was Croatia or Ireland a critical part of Israel support network? The global south has been fairly uniformly against Israel for decades.
And even in the global north, popular sentiment is quickly turning in favor of Palestine.
I have no idea how correct that is or not because the press and halls of power have fully closed rank around Israel. Popular support for Israel might be dropping and once they invade it will almost certainly drop more. But who knows if anything will come of it.
