The disproportionate dimension of things appears to be the Kucinich focus.
The children of Palestinians and the children of Israel both deserve life. But the lives of the children of Gaza are cynically discounted as "human shields". Massacres are being rationalized. Israel's "moral high ground" in Gaza, a growing pile of small bones in a graveyard.
The Administration knows Israel is using US weapons, paid for by US taxpayers, with disproportionate force creating a collective punishment of Gazans, assuring an escalation of conflict, clear violations of the Arms Export Control Act.
Israel was given U.S. weapons on condition they would not be used for aggression or escalation. The outgoing Administration must finally stand for the rule of law, not the rule of force.
Italics added. Same "disproportionate" concerns, Lionel Beehner – Wed Dec 31, 2008, identical text published two places, here and here. That is after the Israeli air campaign began, before the ground campaign.
