The United States is ending its support for Saudi Arabia’s offensive against Yemen, with Joe Biden saying it’s triggered a humanitarian catastrophe.

But Britain is so far refusing to follow the US President’s lead, saying it makes its own decisions about arms sales — so should we continue to arm and support the Saudis? And can you seriously claim to be pushing for peace when you’re also selling weapons to one side in a conflict?

Does the Army have enough battle-ready troops? A previously secret report suggests infantry battalions are running short, and the opposition is demanding action.

Plus, as Britain reveals more about offensive cyber operations against the Islamic State group, we debate the ethics of cyber warfare. Just because you can take down another country’s computer systems, or shut down their power grid, does that mean you should?
