No one is saying she has done a stellar job, but other prime ministers have made mistakes like May.
60 years ago, Britain and the US believed they were on the same page when it came to Suez. How wrong they were.
British prime minister Anthony Eden justified attacking Egypt as necessary to restrain the country's 'dangerous' leader. We still hear similar things before every Western intervention.
There are striking parallels between Eden's handling of Suez and Blair's march into the Iraq War.
Cameron has followed in Eden's footsteps, but in the 1950s the leadership race was a different ballgame.
