I don't know why the Slimes would consider this bizarre. Cristina Fernández de Kirchner is one of their favorite Communist leaders, and they, too, always end up favoring the Palestinians. Also, they never lose an opportunity to argue that international justice trumps American law or any other merely national law.
Their Communist hero (isn't "heroine" kind of sexist?) is just taking their typical daily advice.
Argentina has always been a refuge for anti-Semitic scum.
