Next you going to say South African government shouldn't dismantle apartheid because ANC has song called Kill the Boer.
That's an oversimplification. American public/governtment have a bigger role and pressure in the Palestine/Israel conflict. If you're appealing to the moral authority of the American political class you can't have ambiguous messaging like that. It'll be easily exploited by Zionists whose claim has always been this guys want to cleanse us and destroy us entirely..."look they even have a song for it."
