Yes, but the Americans on the ground are the Gaza Humanitarian Foundation (founded in February), who have been widely criticized, and whose own original leader/CEO, Jake Wood, resigned in May, over significant ethical concerns.
His resignation statement:
"I am proud of the work I oversaw, including developing a pragmatic plan that could feed hungry people, address security concerns about diversion, and complement the work of longstanding NGOs in Gaza.
However, it is clear that it is not possible to implement this plan while also strictly adhering to the humanitarian principles of humanity, neutrality, impartiality, and independence, which I will not abandon.
I urge Israel to significantly expand the provision of aid into Gaza through all mechanisms, and I urge all stakeholders to continue to explore innovative new methods for the delivery of aid, without delay, diversion or discrimination.
I continue to believe the only sustainable path for the long-term is for Hamas to release all hostages, for there to be a cessation of hostilities, and a pathway for peace, security, and dignity for all people in the region.”
Essentially, even its own leader acknowledged and echoed the UN's concerns about GHF's operations. The UN remains willing to work with GHF if they actually start distributing aid in a safe an humanitarian way.
And, per the last page, USAID separately found there to be no real credibility to the "its Hamas" accusations.
I hope you recognize me from other threads (I believe we have interacted) as being far from an anti-Israel zealot, but even the Americans dont seem to believe the Americans, and ultimately seem to be pointing the finger at Israel.
