There has indeed been a step function. Fuelled from Russia and Iran amongst others. For example, Australia has just expelled the Iranian ambassador (the first expulsion of diplomats since WWII) for paying criminals to firebomb synagogues.
France's problems are a function both of history, and push politics. Some of it is endogenous, some of it is externally driven. I have no doubt the same is true in Germany, Netherlands, the UK. Sure, an underlying mass migration pressure is feeding this, but many of the migrants in france pass through, seeking better times in the UK. The ones who stay, are in the main francophone, and appear to bring with them weaker guard lines against radicalism. Thats a huge bummer.
He isn't signalling this because of conviction, he's signalling this because his government wants him to, to continue to back the Netenyahu government. I wouldn't cease trade or relations with France or any EU country on these grounds, its a political dispute about recognition of Palestine, not a statement for or against antisemitism.
You know, and I know, after this evil war ends, Netenyahu is in big domestic trouble. There will probably be another weak, rightist dominated government but the court system will catch up with Bibi. Now .. what does that parallel in the USA?
