Actually he would have, but only if Arafat publicly supported it. (Fat chance.)
You may encounter a lie circulating among Pali terror apologists that the Palestinian Authority was only one day away from initiating a crackdown on militants when the Isralies "spoiled it" all be renewing their targeted killings (after the Jerusalem bus bombing). This is a lie, but there is a grain of truth. There had been a PA meeting the day before in which Abbas tried to get Arafat to publicly support a crack-down, but Arafat refused, and there was no way Abbas would (or could) go ahead under those circumstances.

Dahlan is a terrorist too
4. MOHAMMED DAHLAN Dahlan, 41, is chief of the Palestinian Security Forces in Gaza. He spent four years in Israeli prison for terrorist activities, and was a commander of operations for Arafat's Fatah terror group during the mass "intifada" violence that began in 1987. According to the Israeli government, Dahlan is one of the primary directors of the current terrorist violence against Israelis in the Gaza region.
Masterminded bombing of Israeli bus: Israel Radio reported on October 20, 2000, that "Dahlan was behind the October 18 bombing of an Israeli bus in Gush Katif." The Israeli daily Ha'aretz reported on November 16, 2000, that "members of the Preventive Security Force in Gaza, headed by Mohammed Dahlan, were involved in a series of attacks on Israelis in Gush Katif and Netzarim." Ha'aretz reported on April 17, 2001, that Yasir Arafat "takes an active part in decisions regarding the firing of mortars. The general directives in this regard are passed to Mohammed Dahlan, and from Dahlan to his deputy, Rashid Abu Shabak."
Ordered rocket attack on an Israeli bus: Dahlan is currently a defendant in a lawsuit filed by victims Arab terrorism, including an American citizen as well as three children whose legs were blown off in a Dahlan-directed rocket attack on a bus on November 20, 2000. The Israeli daily Hatzofeh has reported (April 13, 2001) that the Central Intelligence Agency has tape recordings of telephone conversations in which Dahlan can be heard ordering the November 20 rocket attack and other terrorist attacks against Israelis.
Shelters Hamas terrorists: Dahlan told the PA-sponsored newspaper Al Ayam on Oct.26, 1998 that terrorist groups such as Hamas and Islamic Jihad "will not be outlawed."
Hired Hamas terrorists: Dahlan said in an interview with the PA newspaper Al-Hayat Al-Jadidah on Sept.24, 1998, that 25 more Hamas terrorists have been hired by his force, specifically in order to protect them from being arrested by the Israelis.
Praised Hamas terrorists: In an interview with the Hamas newspaper Al-Risallah (cited in Ha'aretz, June 15, 1997), Dahlan said: "The presence of Hamas on Palestinian territory is very important for building the Palestinian homeland."
Threatened violence against Israel: On August 30, 1996, Dahlan said: "The Palestinian Authority does not exclude the return to the armed struggle, and it will then use its weapons." (Jerusalem Report, Nov. 28, 1996)
