Helen Clark, beset by John Key, is watching John Howard to see how (and if) he sees off Kevin Rudd this year. But some places Howard goes, she can't.

Howard's latest cocktail of morality and politics is gobsmacking - send in police and the Army to take the booze off Northern Territory Aborigine adults to cut down sexual and violent abuse of kids, which he calls a "national emergency". Rudd has backed him.

Imagine the mayhem if Clark did that in South Auckland to Maori and Pacific Islanders?

Imagine the stir if Key did? There is no evidential basis to think he would, but he did go big on the "underclass" in January and did illustrate it with a treat at Waitangi for a Maori kid.

The international order offers a parallel.

In 2001, the United Nations developed a "responsibility to protect" doctrine. If a state is seriously mistreating its people or unable to stop others seriously mistreating its people, the doctrine says other states should provide that protection.

Thus in theory, this country has a "responsibility to protect" Zimbabweans. When I aired the nascent doctrine here just before 9/11 I suggested Taleban-run Afghanistan as a candidate. In fact we, the United States and others went into Afghanistan after 9/11. But the aim was to protect Westerners from al Qaeda.

Come back home: if any mother/father/relative/friend (anywhere, not just South Auckland) seriously mistreats a child, on whom does the responsibility to protect that child fall? Logically, the rest of us, via the state and voluntary agencies.

News headlines suggest we have failed that responsibility. Moreover, taking the Afghanistan parallel, are we as a result also failing to protect ourselves? A child not stimulated from birth is less likely to learn well and more likely to fall short of potential as a contributor to the economy and society and thereby to all of us. An abused child may turn later to crime, at a large cost to victims and to taxpayers through the "justice" system and a new generation of abused children.

But how to do our protective bit? Key's charity school breakfasts are too late in life. Steve Maharey's watery "20 hours free" early childhood education is remedial but also too late. For mistreated and under-nurtured 0-3-year-olds, welfare agencies are ambulances, not ladders of opportunity.

Which points to a wider issue for Key and Rudd: to get known in advance as ready for the top job with soundly researched and "road-tested" policy "product" to go with the marketing of the man.
