First, the population of Israel is too small, with more than 8 million in Israel and 80 million in Iran. When there is no water and the army is in short supply, Israel may count on mercenaries to fight.
Second, Israel's land area is too small, only more than 20,000 square kilometers, which is not as big as a county in China, while Iran has more than one million square kilometers, equivalent to the entire area of Zhongyuan 18 provinces in China. Even if there is a missile exchange, it will definitely be Israel. Iran has a vast territory. Without Tehran, Persians can move their capital to fight again. Without Jerusalem, Jews can only go abroad to establish a government in exile.
Considering the one-on-one fight between the two countries, Israel's comprehensive strength is actually much stronger than Iran's. Iran has been sanctioned by the west for many years, and it is very poor, while Israel is very rich. Moreover, Israel has many friends and is an important ally of the United States, Europe and America in Asia. Once the war breaks out, the United States and North Korea will help each other, while Iran's international status is relatively isolated. Even the old neighbors of Arab countries are basically his enemies. Western powers such as the United States, Britain and France have long been enemies of Iran. Iran's friends are only poor and hard countries such as North Korea, and its only big brother is Russia, with more enemies than him.
