First what were these other things the IDF was busy with? Undoing the damage of Oslo in the West Bank. Then kicking Jews out of Gaza and smashing in some heads in Amona. Maybe if the nation and the IDF had its priorities in better order it would have had the ability to prepare for this. Of course if it had not unilaterally withdrawn from Lebanon this would not have been necessary. Olmert of course is learning the lesson well by planning to appease Hezballah and pull out of the West Bank.
