There are over 40 holocaust memorials in the United States and a national holocaust memorial in Washington. The history is unambiguous. Just as with global warming denial, facts do not deter denial. Granted you are writing for an Israeli readership, but from an American point of view, it's hard to see what more could be done to spread the word about the holocaust, a required topic of education in public schools in some states. Far more worrisome should be the kind of thing spread by such as Pam Geller, that Arabs are savages. There surely are Americans who deny the holocaust but there are orders of magnitude more who know absolutely nothing about Arab or Islamic culture, an astounding vacuum considering how heavily involved the U.S. is in Islamic nations.
