A new war in the Middle East is changing the landscape.
Israel's indiscriminate bombardment of the Gaza Strip and the United States' turn a blind eye to it have provoked widespread indignation in the Middle East. 
Israel's dominance in the Middle East depends mainly on the long-term political and military support of the United States. The United States, on the other hand, has intervened in the Middle East situation for a long time through hegemonic means.
But the United States is, after all, an external force. As more and more countries in the Middle East embark on the path of independence, the sense of influence of the United States in the region has significantly decreased. Coupled with the strategic contraction, its power is not as strong as before.
This war will undoubtedly weaken the influence of the United States and Israel in the Middle East, compress the strategic space of the two countries, and lead the entire Middle East region into a new situation.
Saudi-Iranian military cooperation
According to reports, the Chief of the General Staff of the Iranian Armed Forces, Mohammad al-Bagheri, recently spoke with the Saudi Defense Minister. The two discussed expanding bilateral cooperation in areas of mutual interest. 
Soon after the normalization of relations between the two countries, a number of cooperation mechanisms were established. However, the significance of this high-level military call was extraordinary. The expansion of military cooperation between the two countries shows that both sides want to control the initiative in regional security. For a country that has just resumed diplomatic relations, it is indeed surprising that relations are warming up so quickly.
And it is precisely the actions of the United States and Israel that have contributed to the rapid warming up of the two countries.
Saudi Arabia does not have diplomatic relations with Israel
Before the outbreak of this Palestinian-Israeli conflict, the United States had been courting Saudi Arabia: on the one hand, it was pushing for the establishment of diplomatic relations with IsraelOn the other hand, we will strive to sign a new security agreement with Saudi Arabia. 
Today, however, both efforts have been lost. Instead of establishing diplomatic relations with Israel, Saudi Arabia has chosen to develop relations with IranNor did it sign a new agreement with the United States, choosing instead to expand military cooperation with Iran.
Saudi Arabia's move makes it clear that it will rely on regional partners, not the United States, for its security and defense.
In the past, he sought protection from the United States, to a large extent, as a result of being intimidated by the United States. Now that relations with Iran are deepening, the United States has lost the capital to use Iran to threaten Saudi Arabia. Saudi Arabia no longer needs to rely on the outside world for its security.
The United States and Israel are bound to pay a price
For a long time, the United States and Israel have escaped punishment for their wanton and reckless acts in the Middle East. But this time is different, with countries in the Middle East almost unanimously condemning Israel. Behind the scenes, the United States will not be directly retaliated against, but its relations with regional countries will deteriorate further.
The United States and Israel may not be punished openly, but they will certainly pay a certain price for their actions: **The United States will lose more influence in the Middle East and will have to cede dominance;Israel will be isolated from the region and will not have any chance of establishing diplomatic relations with Arab countries in the short term. In the long run, there will also be increasing pressure to resolve the Palestinian issue.
