Dr Einal Wilf has worked with Shimon Peres and been part of the labour party. She has been part of the peace talks, with Arafat in 2000 and then Abu Mazen in 2008. Here she talks for the US congress, about how delusional many Israelis were (herself among them) and how after 7.10 many see things differently. In a simple way she describes the root problem of this conflict that has been going on since 1948 , and it's not related to disagreements about how to split the land between the two sides.
