Like many of you, I have been closely following developments concerning the story in the Swedish daily Aftonbladet alleging that Israeli soldiers "harvested" the organs of Palestinians. At the outset, it should be abundantly clear to everyone that the preposterous allegations in this story are false and unsubstantiated, and what's more, harmful, inciteful and potentially libelous. To be sure, freedom of speech is a bedrock of democracy, and you should rightly be proud that it is enshrouded in the Swedish Constitution. But no less important alongside that freedom is responsibility and accountability. And that is where the most egregious problems with this issue lie, which could lead to the loss of greater values such as diminishing the sanctity of life. The bitter lessons of our shared history teach us that there is a short distance between "anything goes" under the cloak of "freedom of speech" and actions of incitement and violence. In our recent history, for example, it was all too common for similar, unsubstantiated stories against Jews to be printed, which gave credence to the worst atrocities of mankind. Precisely because of that shared history and experience, as Europeans, we cannot accept this type of irresponsible hate speech cloaked as journalism. WHILE MUCH has been made of Swedish government officials' responses, I believe that a fundamental issue has been woefully overlooked; the responsibility that lies with both the article's author and the newspaper's editors. The allegations made in the story derive from dangerous age-old anti-Semitic canards and hateful blood libels and should be condemned as such. But the central issue is that the author of the story and the Aftonbladet editors have been given a green light under the banner of "freedom of speech" to disseminate these false allegations that, in the words of Swedish Foreign Minister Carl Bildt's blog, "can stir anti-Semitism." Words have the power to uplift us, to inspire us and to improve the world around us. But when used irresponsibly, they have the power to stir hatred and violence. And that is the problem at the crux of this matter. To be sure, many Swedes have spoken out against the story and they should be commended, but the silence with which others and the government have treated the issue is deafening - and alarming. As president of a nonpartisan organization representing Jewish communities throughout Europe, I have the responsibility to ensure that issues of importance to the Jewish community are raised - for the betterment of all minorities in Europe. Because we are all Europeans, one and the same. I am proud that we have been at the forefront of joint efforts with the European Parliament, the European Commission and European leaders to foster concrete efforts to promote tolerance and reconciliation throughout Europe. And I hope that as they chair the presidency of the European Union, Swedish officials will continue to enhance these efforts. But as recent trends throughout Europe have shown, unacceptable incidents of anti-Semitism and anti-Zionism are all too real, and in several European nations, including Sweden, are regrettably on the rise. AS WE approach the 70th anniversary of the beginning of World War II and the attempted annihilation of an entire people simply because they were Jews, we must stop and ask ourselves about the values of freedom of speech and the intrinsic responsibility that is bound to that freedom. Yes, freedom of speech is a hallmark of rational and free governments and people. But members of the media have an added responsibility - to fact check and to exercise caution before printing any unsubstantiated article, no matter how many newspapers it may sell. Too many times, incitement and blood libel have masqueraded as "articles" with horrific consequences. Therefore, I implore you as educated, rational European brothers and sisters, to demand responsibility and credibility from your reporters, their editors and their publishers. What's more, editorial integrity, responsibility and accountability must be demanded by government officials. Otherwise, the sacred institution of freedom of speech will be worth nothing more than something to wrap our fish in.
