The Yom Kippur war of 1973 and the invasion of Israel by Hamas of 7 October 2023 are compared, distinguishing similarities and diff erences. The common features are the start of the operation exactly 50 years after the historical precedent, collective character of the attack, its suddenness, and also a huge potential of Arab countries in the world oil market. There are some distinctive features revealed by the author, though. The Arab states are to a bigger extent aimed at conducting negotiations and resolving the confl ict by diplomatic means than in 1973, the structure of the world oil market is different compared to how it was 50 years ago, giving the OPEC members less possibilities for action, as well as fragmentation among the cartel members themselves, decreasing the opportunity agree on the embargo. The author remarks the intention of several Arab countries, in particular, Saudi Arabia, the United Arab Emirates, Qatar, to mediate the confl ict, as well as their aspiration to preserve the trend of restoring relations with Israel. The article highlights the position of researchers about the importance of network diplomacy during confl ict settlement. The shares of countries non entering the OPEC, namely, the United States of America, Russia, Canada are investigated. The conclusion about their important role as oil producers, what limits the possibility of oil embargo,is done. The question of lack of political unity among the OPEC members, as, for example, Saudi Arabia and Iran, Iran and Iraq, is unveiled. The factor of political instability in Libya is emphasised.
