Donald Trump

Military strategists have long warned that war should be waged only if those waging it know what they want to achieve. Herein lies a problem: Washington's war aims in Iran are incoherent.

The Supreme Court has stripped Trump's 'emergency' tariffs of their legal basis, triggering a scramble to recover fiscal losses

Quick, in-and-out precision operations that inflict maximum damage with minimum US casualties have long been a favoured tool of US presidents. Is Trump planning one for Iran?

Tehran isn't likely to easily fold if/when Trump attacks. This means that the longer a military confrontation drags out, the more untenable Washington's position becomes.

Trump will be wondering if a military confrontation with Iran would help or hurt his dwindling popularity at home, making his decision to strike one of the riskiest bets of his presidency

The transfer of sovereign decision-making to external management structures would inevitably cater to the interests of contributors rather than the Sudanese people

The immediate economic impact will be more uncertainty

Iran's vast oil and strategic mineral reserves have moved to the centre of negotiations with the US, which could reshape Trump's calculus

As the US and Iran head to talks in Geneva, competing forces are pulling Trump in opposite directions. There are only two "good" scenarios in front of him, and neither will be easy to achieve.
