In the wake of Vice President Joe Biden’s ill-fated trip to Israel last week, many people would agree with the Israeli ambassador Michael Oren's remark that ‘Israel's ties with the United States are in their worst crisis since 1975… a crisis of historic proportions.’ Like all crises, this one will eventually go away. However, this bitter fight has disturbing implications for Israelis and their American supporters. First, the events of the past week make it clear in ways that we have not seen in the past that Israel is a strategic liability for the United States, not the strategic asset that the Israel lobby has long claimed it was. Specifically, the Obama administration has unambiguously declared that Israel’s expansionist policies in the Occupied Territories, including East Jerusalem, are doing serious damage to US interests in the region. Indeed, Biden reportedly told the Israeli prime minister, Binyahim Netanyahu, in private: This is starting to get dangerous for us. What you’re doing here undermines the security of our troops who are fighting in Iraq, Afghanistan and Pakistan. That endangers us, and it endangers regional peace. If that message begins to resonate with the American public, unconditional support for the Jewish state is likely to evaporate.
