First, Saudi Arabia's oil cost is very low, which can support them to persist for a longer time:
Not long ago, the negotiations between Russia and Saudi Arabia failed, which eventually led to an oil price war between the two countries. Both sides will suffer some losses in this war. After all, if the oil price war continues, it will bring great burden to the economies of the two countries. But in the long run, Russia's advantage in the oil price war is not obvious, because Russia's overall development is relatively slow. In the past few years, Russia's oil profits were not very high, so their savings were relatively limited. If they want to persist for a long time, it is likely to hurt their country's economy. Saudi Arabia's oil cost is extremely low, because they only need simple oil wells to exploit oil, and because the bottom is very thin, the cost is very low. Therefore, even in the price war, Saudi Arabia can still maintain the balance of oil revenue, and eventually they will gradually master the right to speak, leaving Russia in a relatively passive situation.
Second, the oil price war between Saudi Arabia and Russia will improve Saudi Arabia's political status:
If the oil price war between Saudi Arabia and Russia continues, Saudi Arabia's political status will be higher, because Saudi Arabia's actions have a greater impact on the United States, so Trump must face this matter squarely, so Trump needs to please Saudi Arabia and ease the plight of its shale oil enterprises, so Saudi Arabia has gained huge political benefits in the oil price war with Russia.
Third, Saudi Arabia will gradually improve its economic control ability in the Middle East through oil price wars:
Through the oil price war, Saudi Arabia can also strengthen its economic control over the Middle East, because through this oil price war, other countries in the Middle East will be greatly traumatized, so that Saudi Arabia will have more say in the economy.
