Has the Iran war already begun?

This week's attack on the facilities of Aramco, Saudi Arabia's national oil company, was no mere skirmish among proxies. Iran has allegedly fired missiles, loaded on drones, to strike at the heart of the Saudi oil industry. Although Yemen's Houthi rebels claimed the attack, already some fingers are pointing to Tehran. Hence a series of questions: have tensions in the Gulf, which have been escalating since May 2018, already spun out of control? Is the policy of "maximum pressure" on Iran giving way to war? Why did U.S. President Donald Trump escalate tensions right after sacking John Bolton, his hawkish national security adviser? What will be the Trump administration's military response to an attack that it considers a casus belli? As world leaders pack their bags for the United Nations General Assembly's opening session, the world is still trying to answer those questions.
