Advantages: It is a gesture to the Palestinians that would signal a willingness to evacuate settlements and could build confidence by confronting some of his own backers. To the international community, Netanyahu would become the first prime minister to make good on Israeli promises to the US to evacuate the unauthorized settlements. Domestically, most Israelis are likely to support dismantling outposts, which even Israel says are illegal.
Disadvantages: It would force a showdown – possibly even physical – with the most ideological wing of settler movement and alienate other supporters.
