This woman is an example of what happens when a dimwhit who's not too well educated but otherwise is decent, loses her son to a stupid war, and then is betrayed by the very government in which she originally put all her faith (George "W").
It's a classic case of "searching for meaning" by joining the other side.
My pity for her far outweighs my anger at what she's said about Israel, because she is pathetic.
Scientists who've studied Mind Control know full well that putting an individual or group under prolonged, sustained, and extreme stress, when followed by sudden removal of stress and then immediate "re-education" lessons, results in the "brainwashing" of groups or individuals with whichever message you want them to believe.
