I would recommend reading some of the writings of Stephen K. Hayes, a student of Hatsumi's, since I found they shed some light on the deep cultural aspects of ninjutsu. The ninja culture of feudal Japan was an important counter-culture (in) to the predominantly (yo) influence of the bushi, or samurai. Of course read Master Hatsumi's own writings as well!
Remember it was not military defeat in any single large battle that undid the historical influence of the ninja, but stability and a lack of customers (ie. lack of interest). Sadly, history repeats itself somewhat today...which is why, as mentioned in the article, so many of the students now are foreigners.
