The US and Israel are engaging in a rapidly escalating conflict with Iran, which is costing economies billions of dollars a day and is causing a global energy crisis. So far, Iran has fired salvos of drones and missiles at Saudi Arabia, Kuwait, Bahrain, Qatar, the United Arab Emirates and Oman, but these countries have not retaliated. If Iran pushes Saudi Arabia too far, it could force Pakistan to defend its nuclear-armed neighbor. Pakistan's Prime Minister, Ishaq Dar, has been praised for his ally's restraint and assured Saudi diplomat that Pakistan would always stand shoulder to shoulder with Saudi Arabia. The conflict could lead to further "death and destruction" for the region. The US is deploying thousands of troops to the Middle East, raising the possibility of ground operations against Iran.
