In this research, we will explore the theoretical framework of the concept of Lebensraum and how it has evolved over time through the contributions of many thinkers. We will also exAmeene how the practical applications of the concept of Lebensraum have contributed to the negative and hostile attitudes towards it, to the extent of attacking the characters of its adherents or promoters and distorting their intentions. This negative attitude is based on a history of blood and wars that was clearly paved by (aggressive ideas) such as the concept of Lebensraum.It would be appropriate to put in the hands of readers the contributions of contemporary theorists whose intellectual output has contributed not only to enriching the theoretical research of the concept of Lebensraum, but also to its applications. Here, we will choose two of the greatest of these theorists: one who went to prison and then to suicide, leaving his country in the wake of division and the loss of World War II, namely General Karl Haushofer; and the other, who is still drawing the maps of the new Russia as desired by the strong Russian emperor Vladimir Putin.This is not only a comparative study of the ideas of the two men, nor of their role in shaping the dimensions of the political and military strategies of their countries. It is also a study that seeks to know the possibility of similarity in the historical outcomes of both experiences and their final trajectories..
