On the 17th, Saudi Arabia and Pakistan signed a joint defense agreement, which stipulates that any attack on one of the countries will be treated as an attack on both sides.Pakistan is a country with nuclear weapons, and the Gulf Arab countries are increasingly distrusted of U.S. security.

Saudi Arabia signed a formal joint defense agreement with nuclear-armed Pakistan on Wednesday, a move that significantly strengthened the two countries' security partnership over decades in the context of escalating regional tensions.

Currently, Gulf Arab nations are growing concerned about the reliability of the United States as its long-term security guarantor, which was exacerbated by the Israeli attack on Qatar last week.

"This agreement is the result of years of discussions. It is not a response to a specific country or a specific event, but an institutionalization of long-term and in-depth cooperation between the two countries," said a senior Saudi official.

Asked if Pakistan had an obligation to provide Saudi Arabia with nuclear protection under the agreement, the official said: ¡°This is a comprehensive defense agreement that covers all military means.¡±
