It doesn't say Jews have an appetite for war, it says Israel does.
Furthermore, even were he to be doing so, that in itself is anti-Semitic, and the entire blogpost is full of anti-Semitic devices.
Your reply is contradictory: on the one hand, in response to a direct quotation from the blog post you claim that it is "clear" that one can swap "Jew" for "Israeli" in that quotation, and on the other you go on to say that using the word Jew is "provocative, but not outright wrong", which implies that this post is directed therefore at all Jews, and that's basically fine by you in this context.
