It ought not to be difficult to condemn Israel's murder of civilians and bombing of civilian infrastructure including hundreds of private homes, universities, schools, mosques, civil police stations and ministries, and the building housing the only freely-elected Arab parliament.
It ought not to be risky or disruptive to US foreign policy to say that Israel has an unconditional obligation under the Fourth Geneva Convention to lift its lethal, months-old blockade preventing adequate food, fuel, surgical supplies, medications and other basic necessities from reaching Gaza.
But in the looking-glass world of American politics, Israel, with its powerful first-world army, is the victim, and Gaza – the besieged and blockaded home to 1.5 million immiserated people, half of them children and eighty percent refugees – is the aggressor against whom no cruelty is apparently too extreme.
