The objective of this article is to investigate the impacts of “technology” and“geography” on the variance of “offense-defense balance.” This article starts bysummarizing the main causal logic: how “technology” and “geography” affect the“Offense-defense Balance.” It then offers an operational definition and measuringparameter for each of these concepts and thereafter constructs the causal hypothesesbetween “technology,” “geography,” and “offense-defense balance.” In total 16cases have been selected for analysis within three following periods: the First WorldWar (1914-1918), the Second World War (1939-1945), and the Six Day War/ YomKippur War (1967-1973). In conclusion, a controlled comparison study isconducted to test the hypotheses. This results in rather positive results being foundin support of the hypotheses;, in other words showing that military technology andgeography do indeed exert considerable explanatory power on the variance of“offense-defense balance.”
