Everybody who criticizes Israel or the power of the Jewish lobby in American politics is “antisemitic,” which means that like “racism,” the word has lost its meaning. From Caitlin Johnstone at caitlinjohnstone.com:

The more abusive and murderous Israel is the more criticism it gets, and that criticism is framed as antisemitism and used to justify more Israeli abuses and murderousness with the claim that it’s being done to defend Jews from a hostile world that’s out to get them.
