Sharon is a crafty old guy. He knows this long overdue move will cause confusion and position him better to deal with world opinion. He also knows that in days now the Hauge International Court is going to deal with 'the fence'. And later this month he will be in the USA. Plus of course he's already vowed to do things unilaterally; which in reality means he is now pushing the Palestinians into a stillborn, disjointed, and mangled series of controlled ghettos and reservations that bear no resemblance to a real 'Palestinian State' so much talked about.
