Historians reserve the term “watershed” for those rare moments when events do not merely shock the established order but upend it. Think of the fall of the Berlin Wall in 1989, which hastened the end of the Cold War and ushered in an era of American unipolarity. Or the September 11, 2001, attacks in the US, which ignited the global war on terror and culminated in the long, costly entanglements of the so-called forever wars.

In each case, those living through the moment could sense they were witnessing events whose consequences would extend far beyond the immediate crisis. The question now is whether the Iran war belongs in that category. On the world stage, many allies and partners increasingly worry that the United States as a friend is shrinking with extraordinary rapidity. If this is true, what does this mean for international affairs after the Iran war?

Guests are Sir Max Hastings, the British military historian, columnist and former newspaper editor, and John Mearsheimer, professor of political science from the University of Chicago.

President Trump insists the U.S. naval blockade is working -- that Washington’s pressure will force Tehran to return to the bargaining table, with concessions likely to follow. Will Trump get a peace deal with Iran on US terms? Or, with the Strait of Hormuz closed again, could Tehran emerge from this conflict with a blueprint to keep adversaries at bay -- regardless of any restrictions of its nuclear program? Is the US debacle in Iran akin to a “Suez moment” in 1956, that the crisis leads to the end of empire. Is Trump in deep trouble?

Guests are Patrick Cockburn, veteran Middle East commentator for The Independent in Britain, and associate professor Sahar Razavi, director of Persian and Middle Eastern Studies at California State University, Sacramento.

In Islamabad, U.S. and Iranian negotiators have failed to reach even the outline of a peace deal. What now? President Trump has announced a naval blockade of the Strait of Hormuz for ships using Iranian ports and could launch a new wave of strikes on Iran. How will Tehran respond? By going up the escalator ladder, is there now a real danger of an all-out regional war and global recession?

At the same time, widening differences between Israel and Washington may force Benjamin Netanyahu to scale back his ambitions -- whether to crush Hezbollah in Lebanon or to bring down Iran’s battered clerical regime -- in order to preserve relations with the White House. Guests are John Mearsheimer from the University of Chicago and Joshua Landis from the University of Oklahoma.
