Why Trump’s Iran blockade could backfire at sea

The US blockade of Iranian ports has begun.

President Donald Trump is warning any ships that try to disrupt US efforts will be eliminated. Earlier, Iran's parliament speaker said the country would not "surrender under threats".
Weekend peace talks between the US and Iran ended without resolution, with Trump blaming Iran 's unwillingness to end its nuclear ambitions.

Vice President JD Vance has said that it's up to Iran and the "ball is in their court" about furthering peace talks.

So, what exactly is a blockade? Is it legal? And, what could it mean for the wider conflict?

Today on The Front Page, University of Waikato international law professor Al Gillespie is with us to unpack the implications and explore what this move might really achieve.
