War is changing and military strategy no longer delivers victory because of a “short war fallacy”. That warning comes from eminent defence historian Professor Sir Lawrence Freedman, who was part of the Iraq inquiry panel.

He tells Sitrep why he believes military strategists, and their political masters, need to change their mindset, while Professor Michael Clarke explains how the UK’s recent defence review stacks up against that thinking.

Air Chief Marshal Sir Rich Knighton has been confirmed as the new Chief of Defence Staff.  Sitrep assesses what he’ll bring to this newly beefed-up role leading the Armed Forces.

And Dr Victoria Taylor tells us why German reticence to share the history of the Luftwaffe means we may have failed, until now, to fully understand the Battle of Britain.
