Saudi Arabia, a country located on the Arabian Peninsula, is the geopolitical core of the Middle East, far more influential and important than Iran, Egypt, Turkey, and Israel.
Why is Saudi Arabia so important in the Middle East?
Here's why:First, Saudi Arabia: a strategic fortress in the Middle East.
Saudi Arabia, located on the Arabian Peninsula, covers an area of 2.25 million square kilometers. 
It is bordered by the oil-rich Persian Gulf in the east, and is one of the most critical oil routes in the world. It is bordered by the Red Sea to the west and is a waterway connecting the Atlantic, Mediterranean and Indian Oceans.
It is bordered to the north by the valley of the two rivers and the crescent, and to the south by Yemen and Oman. It is bordered by the Red Sea to the west and Jordan, Iraq, Kuwait, the United Arab Emirates, Oman, Yemen and Bahrain. Saudi Arabia is located in a key area of the Middle East and is known as an important hub in Asia, Europe and Africa. 
Geographically, the western part of Saudi Arabia is relatively mountainous and the vast desert in the center and the desert, semi-desert and plains in the east constitute its unique topography. This terrain makes it easy for Saudi Arabia to defend on the Red Sea side and difficult to attack, and if it maintains good relations with Iran, the two sides can form effective cooperation in the Persian Gulf region and further strengthen their control over shipping in the region. At the same time, Saudi Arabia's north-south direction gives it thousands of kilometers of strategic depth, making its geopolitical conditions at sea and on the road extremely favorable, Saudi Arabia is a country with equal sea and land power, occupying a unique and important position in the entire Middle East region. 
Second, Saudi Arabia, the world's oil depots, the big brother of the OPEC organization.
Saudi Arabia accounts for 16% of the world's oil reserves, ranking second in the world, and accounts for 11% of the world's oil production. Saudi Arabia is the big brother of the oil organization OPEC, and has a great voice in the OPEC organization, so it has a great voice in the oil production of the Middle East and plays an irreplaceable role in the world's oil industry. 
Saudi Arabia led Arab countries to use oil**, which severely hit the economies of the United States and the West.
In October 1973, the Fourth Middle East War broke out, and the Organization of the Petroleum Exporting Countries (OPEC) announced an oil embargo and suspended exports in order to combat Israel and the countries that support it, resulting in the price of oil**. At that time, it rose from less than $3 a barrel in 1973 to more than $30. Under pressure from Saudi-led oil producers, the EC took a stand in support of the Arabs in late November, and the oil embargo was lifted by EC members (except the Netherlands). On November 22, 1973, Japan could not resist the pressure and announced that it would side with the Arabs.
Only the United States and the Netherlands were isolated. 
During the first oil crisis in 1973, cars lined up at gas stations. ）
The embargo lasted until 18 March 1974.
The oil war launched by Saudi Arabia led by the oil countries had a great impact on the United States and a few other countries that relied on cheap oil, leading to the largest economic crisis since World War II.
Industrial production fell by 14 percent in the United States and more than 20 percent in Japan, and the pace of development slowed significantly in all industrialized countries. The United States was the most affected, and Nixon, who was the United States at the time, had to declare a national emergency.
As a result, the Arab countries have strengthened their economic strength, and tens of billions of petrodollars have flowed to the Middle East, and according to statistics, the price increase alone has caused the oil revenues of the Arab countries to soar from $30 billion in 1973 to $110 billion in 1974. Oil** is far more powerful than Iran's resistance to the United States and the West. In this Israeli-Kazakhstan conflict, due to Saudi Arabia's policy of neutrality, the arc of resistance led by Iran is very, very weak against the United States and Israel. 
Third, Saudi Arabia is the spiritual leader of the Islamic world, and its influence is far greater than that of its rival, Iran.
1. According to 2022 statistics, there are 18400 million Muslims. Sunnis, led by Saudi Arabia, make up more than 85 percent, while Iranian-led Shiites outnumber Saudi Arabians.
2. The three holiest places in Islam: Mecca, Medira, and Jerusalem. Mecca and Medira are located in Saudi Arabia, and Mecca is the birthplace of Islam and has the holiest building in Islam - Macbeth.
Every year, millions of Muslims travel to Mecca for the pilgrimage. 
3. The Saudi royal family calls itself the "servant of the two holy sites", and this status has earned Saudi Arabia respect and influence in the Islamic world.
Fourth, Saudi Arabia's diplomacy is in full swing, and while it has in-depth exchanges with the United States, it has also made good friends with major countries such as China and Russia.
The above four reasons determine that Saudi Arabia is the geopolitical core of the current Middle East world, and its influence far exceeds that of Egypt, Turkey, and Iran.
