This article discusses NATO - Russian security relations within the fr
ame of <<Partnership for Peace>> (PFP). In accordance with a <<two-tie
red modular design>>, the article argues that the PFP concept can prom
ote collective great power cooperation in Europe and contribute to les
s polarization between NATO and Russia. The analysis is based on a geo
political perspective concerning NATO activity in Central Europe and R
ussian activity in the CIS area. PFP, the article argues, might be a s
trategy to show reciprocal geopolitical restraint. Eventually it will
prepare for a security order de facto guaranteed by the western great
powers in NATO and Russia in concert, as the great power <<tier>> in a
European security system. In this respect, the kind of relations betw
een the great powers as a first <<tier>> and a second <<tier>> of less
er powers, within the framework of PFP, is of importance for a great p
ower-guaranteed system.
