What are the lessons for IDF force build-up following the Hamas attack on October 7 and the Iron Swords War? A recent article by Prof. Azar Gat concludes that "there is no need to increase the scope of the forces and the existing force build-up should be continued, the main [element] of which is investments in technologies that are the key to the advantage of the IDF on the battlefield and for the current achievements." We do not agree with this conclusion and believe it to have negative strategic consequences. The continuing inability of the IDF to realize the goals of the current war is mainly the result of a lack of ready and available maneuvering units, a lack that military technology cannot compensate for no matter how good it is. If the IDF is to be able to fulfill its responsibilities, it needs more well-trained maneuver divisions to resurrect the territorial defense organization as well as maintain technological superiority.
