This article concentrates on the question of how the expansion into space, which was part of the information and space technology revolution, affected patterns of warfare and concomitantly affected force build-up in the US and Israeli military forces . It will describe and analyze the influence of space technologies on the changes that have occurred in military thinking and in warfare patterns and the ensuing effect on the structure of military force in the US and Israel in the last 25 years. This research indicates that the ability to develop space technologies and to attain power in space is not exclusive to great powers. Small countries with relatively modest budgets can also excel and exploit opportunities which were unavailable to them when the emphasis was on size and quantity instead of on high quality as is the case in the information and space age.
