Today's blast outside Jerusalem's central bus station shattered a long period of relative peace and security in Israel's capital and largest city. Jerusalem had not been hit by a bomb for nearly seven years, since the al-Aqsa Martyrs' Brigade killed two Israelis on September 22, 2004.
There have been a couple other terror attacks in Jerusalem since 2004 (a Palestinian terrorist killed eight students and wounded eleven while shooting up a religious school in 2008, and later that year when a terrorist commandeered a bulldozer, killing three and wounding fifty in Jerusalem). The most recent terrorist attack (before today's) occurred outside of Jerusalem, with the barbaric slaughter of a Jewish family in the West Bank earlier this month. A terrorist invaded their home in the dead of night and stabbed to death Ruth and Udi Fogel and three of their children, 11-year-old Yoav, four-year-old Elad, and three-month-old Hadas.
While Israel continues to face terrorist attacks to a degree that other nations do not, as this chart shows, there's been a dramatic decrease in suicide attacks and other bombings in Israel over the past decade--a drop in violence that coincided with the construction of the security fence. It's not as though terrorists have lost their will. It's that they've been thwarted, with rare and horrible exceptions like today, by the fence and stepped up intelligence and security operations.
