The section that connects to the beach in Gaza was rebuilt nearly two weeks after heavy storms damaged it and abruptly halted what had already been a troubled delivery route.
Let me put it this way- large chunks of The Odyssey are Odysseus being caught in a big storm at sea. So you would think the U.S. military would have heard about something that's been known since the bronze age.
What is the population of Gaza? Maybe 2.1 million in the Gaza strip? Various search engines give results between 1/2 million and 5 million, a rather wide variance. This article says the U.S. hopes to deliver 1 million pounds of food every 2 days. The average person eats between 3 and 5 pounds of food per day. It's not enough food even for the lowest population estimate. OTOH, every bit of additional food helps and is good news.
It is because it broke down after the first delivery and the first delivery got blocked by the IDF and wasnt distributed. So the Pier didnt really deliver anything yet.
It is also still far too little and the US could force Israel to open all borders to let in as much aid as is actually needed by stopping to send them weapons and provide diplomatic cover. Plus if the US would apply sanctions, Israel could be forced to retreat from Gaza and finally start upholding international law within a few days.
