WASHINGTON >> The Biden administration is stepping up criticism of Israel for not doing enough to improve humanitarian conditions in Gaza as a 30-day deadline looms for Israeli officials to meet certain requirements or risk potential restrictions on military assistance.

The administration also is condemning recent violence against Palestinians in the West Bank by extremist Jewish settlers and says those responsible must be held to account.

State Department spokesman Matthew Miller on Monday gave Israel a “fail” grade in terms of meeting the conditions for an improvement in aid deliveries to Gaza laid out in a letter last month to senior Israeli officials by Secretary of State Antony Blinken and Defense Secretary Lloyd Austin.

He said there were still nine days until the deadline expires, but that limited progress thus far has been insufficient.

“As of today, the situation has not significantly turned around,” Miller told reporters. “We have seen an increase in some measurements. But if you look at the stipulated recommendations in the letter, those have not been met.”

A day before the U.S. election, the Biden administration called out its close ally, with support for Israel a key issue for many voters and the humanitarian crisis for Palestinians also a factor for many in the race. Former President Donald Trump and Vice President Kamala Harris have been competing for Muslim and Arab American voters and Jewish voters in battleground states like Michigan and Pennsylvania.

Among other conditions, Austin and Blinken’s letter from mid-October said that Israel must allow in a minimum of 350 trucks a day carrying desperately needed food and other supplies for Palestinians besieged by more than a year of war between Israel and Hamas. By the end of October, an average of just 71 trucks a day were entering Gaza, according to the latest U.N. figures.

“The results are not good enough today,” Miller said. “They certainly do not have a pass. … They have failed to implement all the things that that we recommended. Now, that said, we are not at the end of the 30-day period.”

He would not say when asked what the U.S. would do when the deadline comes up next week, just that “we will follow the law.”

Similarly, Austin has been reinforcing “how important it is to ensure that humanitarian assistance can flow and flow faster into Gaza” in calls with his Israeli counterpart, Maj. Gen. Pat Ryder, Pentagon press secretary, told reporters Monday.
