Why has America risked it all in Gaza?

It has now been close to 10 months that Israel has been waging a genocidal war in Gaza. Its army has violated nearly every facet of international humanitarian law in its relentless assault on an unimaginably vulnerable population. Israel has denied the Gaza concentration camp the bare necessities of life -- food, water, medicine, sanitation, electricity and fuel. And its targeting of civilian infrastructure has made the majority of Gaza residents homeless. No Israeli military goal requires the total destruction of Gaza.
