the PM gets slated 'cos thats his job. He chose to spend his working life trying to prove how good a statesman he his, we pay him a handsome 5 figure salary for the rest of his life.
If things don't get better, then the PM gets stick about it, thats (apparently) is the democratic model which we are trying to export to the middle east.
Don't be confused, its quite simple really, the sort of people who have a desire to become politicians are the sort of people who need the world around them to think that they are selfless servants of the greater good.
Unfortunately, people who need other people to have this or that opinion of them, seldom have the capacity to do any good. They are too hung-up on public opinion. As a result, the timewasters with ego-problems end up bitching and fighting in public, while the rest of us get on with our lives and try to focus on the little bits of life we actually come into contact with. This results in the ideal politician being someone who can put on a public face, wear it convincingly and fool the simple audience who have been hypnotised into wishing they were the ones on the stage.
The CIA realised this in the seventies and arranged for an experiment to take place whereby a B movie actor was installed in the Whitehouse. They believed that not even the US electorate would fall for that for long, but how wrong they were! From then on the US political sphere has actually moved into the control and jurisdiction of the secret service and the accountants; thus leaving Hollywood to provide the next generation of political masters. ("They'll be back!")
chuck your cross at the paper cos it's all we've got to call our democratic right, but don't be under any illusion, the civil service are the mechanics of government and the civil service has little (if anything) to do with politics. The politicians are just the modern day equivalent of court jesters, happy smiling fools just waiting to be adored by us simple, common folk!
