Maybe Israel thinks the Obama administration won't approve

But they know the Bush administration understands completely and approves:

John Ging, the head of the UN relief agency in Gaza, described the situation there as "inhuman".

"We have a catastrophe unfolding in Gaza for the civilian population," he said. "The people of Gaza City and the north now have no water. That comes on top of having no electricity. They're trapped, they're traumatised, they're terrorised by this situation.

"They're in their homes. They're not safe. They're being killed and injured in large numbers, and they have no end in sight. The inhumanity of this situation, the lack of action to bring this to an end, is bewildering to them."

The UN has been particularly angered at the contention of the Israeli foreign minister, Tzipi Livni, that there is no humanitarian crisis in Gaza.

Ging also accused Israel of a campaign of destroying public buildings vital to the administration and governance of Gaza.

"The whole infrastructure of the future state of Palestine is being destroyed," he said. "Blowing up the parliament building. That's the parliament of Palestine. That's not a Hamas building. The president's compound is for the president of Palestine. Schools, mosques."

And it's Hamas' fault for starting this war, even though the Palestinians have been suffering:

While firing rockets at civilians is a crime so, too, is the Israeli blockade of Gaza, which is an egregious violation of international law and the Geneva Conventions.

According to the UN, most of Gaza's 1.5 million Palestinian refugees subsist near the edge of hunger. Seventy per cent of Palestinian children in Gaza suffer from severe malnutrition and psychological trauma.

Medical facilities are critically short of doctors, personnel, equipment, and drugs. Gaza has quite literally become a human garbage dump for all the Arabs that Israel does not want.

Gaza is one of the world's most-densely populated places, a vast outdoor prison camp filled with desperate people. In the past, they threw stones at their Israeli occupiers; now they launch home-made rockets.

Call it a prison riot, writ large.

Exactly.
