Should Key apologise to The Kaiser also?

The Herald reports:

Prime Minister John Key today said he won’t be apologising for New Zealand’s role in the invasion Gallipoli a century ago.

On the eve of the bloody First World War conflict’s centenary, a prominent Turkish-New Zealander has called on the Government to say sorry for the offensive that claimed 86,000 Ottoman lives – almost twice the number of Allied soldiers killed.

But today when Mr Key was asked if he should apologise on behalf of New Zealand for the bloodshed of 100 years ago, he replied: “No.”

Why only apologise to Turkey? Should we also apologise to Kaiser Wilhelm II?
