The news about yesterday's suicide bombing in the Israeli town of Dimona is that it's news. In 2002, at the height of the second intifada, 451 Israelis were killed in terrorist attacks, including 14 suicide bombings. By contrast, yesterday's attack, which killed one and injured 11, was the first of its kind in more than a year.
This didn't happen by accident, or because Palestinian radicals have somehow become less hostile to Israel. Responsibility for yesterday's attack was claimed by the Al Aqsa Martyrs' Brigade, which is affiliated with President Mahmoud Abbas's ostensibly moderate Fatah party. Islamist Hamas remains even more ardently dedicated to Israel's destruction, a point it emphasizes with its rocket barrages at southern Israeli cities close to the Gaza Strip.
Instead, the difference has come because of Israel's increasingly successful antiterrorist efforts. Key to that success has been the construction of its ostensibly "illegal" security fence, its equally "illegal" targeted assassinations of key terrorist leaders, its "disproportional" attacks on terrorist enclaves in Jenin and elsewhere, and other actions that saved innocent lives but which much of the international community deplored.
One of the most common arguments against Israel's actions is that it would feed a "cycle of violence." It's fair to say that what happened is closer to the opposite. As Israel put pressure on terrorist leaders, they were forced to spend their time running for their lives rather than planning the next attack. As Israel set up physical obstacles to terrorism, the need for large-scale military incursions declined, allowing a semblance of normal life to return for Israelis as well as Palestinians. Contrary to the conventional wisdom, Israel proved that terrorists can be defeated -- a lesson that applies equally in Iraq.
