Why? There are four primary reasons.
First, I admit, it has become simply exhausting to maintain the ambivalence, the hugging and the wrestling, the endless fence sitting. My love of Israel has turned into a series of equivocations: “I do not support the expansion of settlements, but the Palestinians bear primary responsibility for the collapse of the peace process in 1999.” “The Israelis acted overzealously in Gaza, but they must be entitled to defend themselves against rocket attacks.” “Yes, the separation wall is odious, but it is also effective and necessary.” Yes, but; no, but; defend, but. At some point, the complexity and ambiguity wears one out, particularly when the visuals on the anti-Israel side are so compelling, and so stark: walls, tanks, checkpoints.
