(JNS.org) Polish-American Holocaust historian Jan Tomasz Gross is being investigated by a Polish state prosecutor for potentially publicly insulting Poland with a statement he made about Polish violence against Jews during the Holocaust. Insulting the government in such a manner is a criminal offense in Poland that carries a prison term of up to three years. In an article published last year by Project Syndicate, Gross said that Poles killed more Jews during the Nazi occupation than the Germans, a claim that flies in the face of the popular view in Poland that the country responded to the German invasion nearly always honorably. Gross made the statement in the context of criticism over Europe’s response to the current migrant crisis, calling Europe’s opposition to accepting more refugees “heartless” and rooted in the continent’s “murderous past.” “Consider the Poles, who, deservedly proud of their society’s anti-Nazi resistance, actually killed more Jews than Germans during the war,” Gross wrote in the article.

Gross, a professor at Princeton University, was questioned for five hours on April 12 in Katowice, Poland, but has yet to be told whether he would be charged with the crime. “I told him straight that I was not trying to insult the Polish nation. I was trying to raise awareness about the problem of refugees in Europe,” Gross said. “I am just telling the truth and the truth sometimes has a shocking effect on people who are not aware of what the truth is.”

In addition to the potential criminal charge, Polish President Andrzej Duda may strip Gross of an Order of Merit he received in 1996.
