Military conflicts are easy to start and painfully difficult to end.

As Donald Trump's war with Iran enters its fourth month, Jon Allen joins Jeremy Kinsman and Peter Donolo to discuss how a conflict once promised to be short and decisive became a global crisis. The Strait of Hormuz remains closed, energy markets are under pressure and America's allies are reassessing what U.S. leadership now means.

Allen, Canada's former Ambassador to Israel, argues the conflict was shaped by the egos of both Trump and Benjamin Netanyahu, and by a miscalculation about how Iran would respond once attacked. The conversation turns to possible negotiations, the limits of Israeli and American leverage, the humanitarian catastrophe in Gaza and the wider fallout for NATO, the G7 and countries that once relied on American stability.
