Yes, Israeli Prime Minister Benjamin Netanyahu did tweet about Charlie Kirk before he died. Netanyahu described Kirk as a "lion-hearted friend of Israel" who was murdered "for speaking truth and defending freedom." He mentioned that he had spoken to Kirk only two weeks prior to his death and had invited him to Israel, but sadly, that visit would not take place. Netanyahu called Kirk an incredible human being whose pride in America and belief in free speech would leave a lasting impact.
Netanyahu also publicly mourned Kirk, calling him a "once-in-a-generation" figure and reflected on their last communications. He praised Kirk's dedication to strengthening the bond between the U.S. and Israel and his advocacy for Judeo-Christian civilization, highlighting Kirk's support for Israel up until his assassination.
