Slovenia has been perceived as the so called fore runner in the association procedure to the NATO. NATO political and military representatives and experts(especially USA) have presented Slovenia as a model or case study for other candidate states in the association procedure. However, the public support to the association procedure has decreased in the last few months. Themost important reason for this may be the anxiousness of the Slovenian people about a deployment of the foreign armed forces on the territory of Slovenia. A thorough analysis of the public opinion has shown a great deal of indistinctness and lack of knowledge in the above-mentioned field. Presence ofthe foreign armed forces on the territory of Slovenia is perceived as a gradual limiting of the hard-acquired independence and a disturbing factor in the social environment. Presence of a foreign military base and consequently foreign armed forces causes different effects in the selected area. Scientificinvestigation of these effects is usually done after the base closure. Many international scientific groups have published their analyses and results, which emphasized negative experiences of the host states. All problems began at the time when the bilateral agreement between two states wassigned. Since the rules determining life, existence and responsibility for all the damage caused by the military base were not specified, tensions between the two states appeared. All the problems had to be solved by the local inhabitants and government, affected by the existence of the military base. This is why a possibility of the deployment of foreign armed forces and their building of the military bases has to be discussed before Slovenian Government takes any steps and accepts decisions which could cause negative effects on the local inhabitants and the Republic of Slovenia.
