On the day the White House said the Israeli military should do more to protect Palestinian civilians in Gaza, the US confirmed it had agreed to supply the same military with more ammunition.
The Obama administration has hardened its criticism of the shelling of a UN school in Gaza calling it "indefensible" and saying there is little doubt the Israelis were responsible.
"We need our allies in Israel," said administration press secretary Josh Earnest "to live up to the high standards they have set themselves". Meanwhile those same allies were being invited to help themselves to more of the US arms stockpiles in Israel.
Duplicitous double standards or another sign of the complexity of US-Israeli relations? Depends on your point of view.
There is no doubt the Obama administration is concerned and frustrated by Israel's conduct. There is also no doubt the administration will continue to support it to the hilt for as long as required.
Frustrated not least because of the trashing of the US Secretary of State John Kerry by Israeli cabinet ministers and media after his efforts to broker a ceasefire.
The Obama administration has not hidden its fury at the personal attacks on America's chief diplomat by senior members of the Netanyahu government.
The mounting civilian suffering is a concern to the US, for humanitarian and diplomatic reasons.
What's left of America's standing in the Arab world is further undermined by gruesome pictures of slaughter caused by US-supplied weapons being fired into Gaza.
A lot has been made of the dysfunctional relationship of the two countries' leaders.
Bibi and Barack have had more than their share of differences, and none of the political intimacy of George W Bush and Ariel Sharon.
But these days Israel can take US support for granted far more than it could back then.
