Conclusion
The study of the pattern of geopolitical relations between the two countries after the Iranian revolution shows four periods of relations between the two countries, which in every four years dominated the pattern of interaction (cooperation) and conflict (conflict) between the two countries. Accordingly, in the first period of the geopolitical relations between Iran and Saudi Arabia after the Islamic Revolution, until 1989, Saudi withdrawal from Iran became a threat and an enemy, and from Saudi Arabia's perspective, Saudi Arabia was seen as an unjustified regime. In the second period of geopolitical relations from 1989 to 2001(the formation of the11 Septamir incident), with the change of orientation of Iran's foreign policy and the diminution of ideological approaches, regional and international developments, such as the Turkish-Israeli coalition, the Saudi-political and economic problems, and Confronting Iraq's action to change the regional balance of Kuwait's occupation, on the other hand, along with the collapse of the bipolar system and the creation of a monopoly power distribution system in the international system and Iran's pragmatism towards the outside world, Iran-Saudi relations out of the geopolitical conflict. Turning to geopolitical interaction, the two countries took one The other was changed to "enemy".The continuation of this trend in the third era of relations in the year 2001, along with the September 11th accident, will lead to Iran and Saudi Arabia becoming closer to Iran and Saudi Arabia, along with regional and international confidence building on Iran and its alignment with the Saudi rulers' approach. Although in the second and third periods of relations, some differences and geopolitical rivalries were present between the two actors, the lack of identity along with the adjustment of structural pressures led to the formation of a geopolitical interaction pattern in relations. The fourth round of relations between Iran and Saudi Arabia since 2005 (simultaneously with the Arab revolutions) was accompanied by a geopolitical exchange of interaction from geopolitical controversy. During this period, the confrontation and ideological and geopolitical rivalries intensified simultaneously. The distinction of this period with the first period was the departure of Saudi Arabia from a conservative orientation and an active and invasive approach to foreign policy and its ideological prominence and support for radical Sunni / regional conflicts. Finally, it can be said that what causes the rotation in the geopolitical relations between the two countries is the opposition and competition of identity and geopolitical factors along with the pressures of the world powers.
