According to Ynet, a Chabad delegation from Brooklyn led by Rabbi Yehuda Leib Groner met with with Prime Minister Ariel Sharon.
Chabad opposes disengagement but also opposes all non-violent forms of protest (that would include blocking highways, burning tires, vandalism, etc., along with more violent actions).
Ynet also notes that:
At this time it is still unclear which line the Chabad-Lubavitch movement would adopt once disengagement rolls around. The movement’s leadership is considered moderate, but the more radical branch has vowed to thwart the pullout and has called on soldiers to refuse evacuation orders.
Will the 'civil war' in Israel lead to a heightening of the civil war within Chabad? Only time will tell.
