Western leaders supporting Israeli war crimes in Gaza are making the same blunder European leaders did in 1914: fail to account for blowback. There are 2 billion Muslims in the world. None are happy about Gaza. Biden has brought millions of unvetted migrants across the border. Among them are thousands of military-age males from countries that hate Jews. The likelihood of reprisals against Jews in America and elsewhere is undeterminable at this time but very likely greater than zero.
