Although the war in Gaza is still in its early stages, Israel must begin learning from it now. The next challenge, a war in the north, might be imminent. The primary lesson taught by the war in Gaza is that no military-size terror threat should ever again be allowed anywhere on Israel’s borders. Such threats should be removed by force on the other side of the border. A concentrated force-design process, focused on four or five plans, in addition to basic preparations will enable the creation of a sharper and readier military force. Israel should focus on embarking on about two years’ worth of preparations for the next war.
