Tony Blair embarked on Mission Impossible having been advised of the likely outcome. There was little planning or forethought and so the inevitable happened.
It seems incredible that those who cry democracy loudest practice it the least. Although we pride ourselves living in a democracy the whim of the elected leader can carry the decision based on the particular views, prejudices, whims of a single person. This has happened repeatedly in Britain’s history not least over Palestine where both Jews and Palestinians blame the British for todays chaos. Many decisions were made on the basis of belief based on sentiment and religious upbringing so that the Zionist cause had blind support.

There are many more examples.
