Arash of audacious attacks on mosques, Muslim cemeteries and Israeli military bases have trained a light on the rising threat of Jewish extremists _ and the country's long history of failing to rein them in.
Over the past two years, few extremists have been arrested and fewer still prosecuted in dozens of assaults. This week alone, extremists were blamed for a pair of mosque burnings as well as an attack on a West Bank military base that injured a top Israeli commander.
The violence has prompted rare attention from Israeli leaders, who have begun to call the perpetrators "terrorists" _ a term usually reserved for Palestinian militants.
"Israel must not be overrun by a group of people who represent a grave danger to its essence and existence," President Shimon Peres, a Nobel peace laureate, said Thursday after meeting with mainstream West Bank settler leaders.
"We won't let them attack our soldiers. We won't let them ignite a religious war with our neighbors. We won't let them desecrate mosques. We won't let them harm Jews or Arabs," Prime Minister Benjamin Netanyahu, told a meeting of his Likud Party late Thursday.
Moderate parliamentary opposition leader Tzipi Livni this week said the extremists were pushing Israel to the edge of civil war.
Critics say the violence is the result of authorities' long-standing policy of treating Jewish extremists, usually connected to religious elements in the settler movement, with kid gloves. Instead they have tended to focus on thwarting attacks by Palestinian militants.
"The tendency of the military and the police is to see their own role as protecting the settlers, the Israeli citizens, from the Palestinians, rather than to fulfill their proper role, which is being responsible for keeping order and public safety in territories under military authority," said Gershom Gorenberg, an author who has written extensively about the settler movement.
Hard-line settlers believe Israel has a God-given right to the West Bank and east Jerusalem, territories Israel captured in 1967, and reject Palestinian claims to those lands.
The attacks on mosques and other Palestinian targets are known by the label the extremists coined, "price tag" _ suggesting they are retribution for government operations like dismantling illegally built settlement structures.
