Iran is a theocratic country with strong dominance and strength, so it far surpasses Saudi Arabia in terms of strength. As a country with rich oil resources in the world, Saudi Arabia has a lot of resources and is also an ally of the United States. However, Iran has been sanctioned by the United States all year round, so many of them have been subject to economic sanctions.
In fact, these are all superficial reasons, and in fact, Saudi Arabia’s military strength is not weak. It is also the most advanced and powerful in the Middle East. The most critical reason why Saudi Arabia is so weak is that it has a small population. Although Saudi Arabia is vast in area and is the largest country in the Middle East, its population is too small. There are only more than 30 million people in Saudi Arabia, and less than half of them are foreigners. There are only 20 million locals, which is not even comparable to countries such as Syria.
In the Middle East, national strength is still based on population. The more people there are, the greater the power. When the economy is similar, a large population is a symbol of strength. The most typical example is Egypt, which is very poor in the Middle East. However, because Egypt has the largest population in the Middle East, close to hundreds of millions, it has always been a Diaoyutai in the Middle East and is an unshakable power in the Middle East. Although Saudi Arabia is very rich and Iran is far inferior to Saudi Arabia, Iran's military power is strong. Military power represents the strength of a country. Only strong military power can have a place in the right to speak. As an old Chinese saying goes, it is "in the barrel of a gun." "To change the political power", the military power will be hardened.
Many countries in the Middle East rely on oil resources to export a lot of oil and obtain a lot of funds. Iran has been subject to many economic sanctions by the United States, but Iran is also developing on its own.
