North Korea and Russia join forces

First it was sending ammunition, then troops for the war in Ukraine, now North Korea has signed off on a formal mutual-defence treaty with Russia.

NATO’s new Secretary General has called it a threat to our security. Defence researcher Joseph Dempsey, who’s spent years uncovering the secrets of North Korea’s military, explains the risk, and what’s in it for Moscow and Pyongyang.

On the Korean peninsula shots have been fired across the border, more missiles have been tested, and there have been nuclear-capable shows of force in the skies.  Lieutenant General Andrew Harrison draws on his two years helping protect the armistice to assess the scale of the tensions.

And we get the lowdown on China’s new stealth jet, which has a remarkably similar look and name to the US and UK’s fifth-generation fighter.
