The chapter explores Hamas’s strategic analysis and study of Israel and the IDF. As part of its intelligence warfare, Hamas strove to increase its knowledge of the enemy. This chapter describes Hamas’s accumulation of intelligence about Israeli weaponry, IDF units, Israeli battlefield tactics, operational training, and so on. The organization particularly sought information about the capabilities of Israeli armored vehicles in order to inform its use of anti-tank weaponry. The chapter also illustrates how Hamas disseminated this knowledge in its ranks. This chapter goes on to analyze Hamas’s operational preparations for war after Israel’s withdrawal from the Gaza Strip. Further, it examines Hamas’s ongoing assessment of the possibility and characteristics of a large-scale Israeli attack, and in particular the analysis of the Israeli political and social situation used by Hamas in order to form such an assessment. In this manner, the chapter discusses the influence of Hamas’s “enemy image” of Israel – an image based on the organization’s Palestinian Islamic ideology as well as its interpretation of events and social processes in Israel – on the organization’s assessment of its enemy. The chapter also sheds light on the organization’s difficulties in strategic analysis of Israel.
