Attempting to master change and collectively drawing lessons from current international relations in order to define the targets and face in common challenges of security in the mediterranean may, inherently, steam up from opportune and reliable but highly ambitious, conception. Opportune conception, in fact, given the transformations the world has witnessed since the post cold war era which have drawn the interest of international community as a whole on the acuity of existing solidarity networks and security doctrines behind which states stand to ensure their survival or defend their own interests. Surely ambitious also, is this conception with regard to the implicated adaptations in a context deeply marked by a variety of insecurity sources, at a time when discrepancies between states tend to increase. To these assumptions, however, must be added other aspects more directly linked to the controversy on the security in the Mediterranean along a brief presentation of the current situation which will permit us-firstly- to apprehend with more accuracy the main cleavages determining the differences in perceptions and in this vein to foresee- secondly-the eventual actions left to the borderer states and their partners alike, to pave the way for future evolution.
