The Green Party leader compared the arch-terrorist to former South African president Nelson Mandela, citing an unverified quote by the anti-apartheid activist echoing the same sentiment.Polanski proposed tracking Brits who serve in the IDFLast week, Polanski caused further controversy by signing an open letter calling for the government to investigate IDF veterans with UK citizenship and screen them at the border.“The IDF has been accused of horrific war crimes in Gaza by the UN Human Rights Council & Amnesty International,” Polanski said on X/Twitter on Thursday. “It is just common sense that those involved in war crimes should be held to account.”The letter, organized by Declassified UK and the International Center of Justice for Palestinians (ICJP), demanded that the UK implement airport disclosure requirements for IDF service, that Israelis, or those traveling from Israel, be subject to screening for war crimes, and that investigations and prosecutions of veterans and service members be conducted.Jailed Fatah official Marwan Barghouti (credit: REUTERS)Polanski had collaborated in his Instagram post on Barghouti on Sunday with an organization that on Wednesday attempted to erect a statue of the terrorist in London's Parliament Square on Wednesday.Activists were intercepted by officers and forced to remove the bronze figure.The Free Marwan Now campaign said one day a statue of Barghouti would stand in the square alongside other bronze statues of figures such as Oliver Cromwell, Benjamin Disraeli, and Nelson Mandela."Marwan will take his rightful place alongside other civil rights leaders," the activist campaign said in an Instagram post shared in collaboration with climate activist Greta Thunberg and actors Mark Ruffalo and Liam Cunningham.Like Polanski, campaigners compared Barghouti to Mandela."Nelson Mandela was once politically isolated and labeled a terrorist before being recognized as a global symbol of freedom and justice," said the campaign. "Marwan Barghouti faces a similar fate."Follow us on Google
