Cesarani rejected suggestions that incidents such as the attack on a Kosher shop in Paris following the "Charlie Hebdo" shooting in January 2015 were a sign of universal anti-Semitism. He wrote that "The current hysteria about the 'rise of anti-semitism' and the flight of Jews from Europe is deeply regrettable. There is no 'wave' of anti-semitism." The basis of his argument was that Jews were not socially or legally isolated "as they were in the 1930s and 1940s, but find themselves enjoying unprecedented solidarity." He further emphasised that Jewish communities "on both sides of the English Channel rallied and continued to thrive" following targeted attacks by Palestinian Arab terrorists in the 1970s and 1980s and wrote that the "current press hyperbole shows not only ignorance about what the situation was like 70–80 years ago, but what it was like just 20–30 years before now." He also attacked Israeli Prime Minister Benjamin Netanyahu for "fear mongering" and asserted that Jews, non-Jews and Muslims were standing "shoulder to shoulder" against a common terrorist threat.
