It is not Hamas taking the aid. If the US wants to prove to be sincere and solve this crisis they need to stop arming the people causing this famine and murdering the people.
Also the only answer to reduce famine is to flood the place with so much food, that no one is fearing to not have enough anymore and become desperate to take more for their families and themselves.
The US said it wants to deliver about 800 tonnes every day. Assuming one meal to be 500g and three meals per person per day, that could merely amount to food for 533,000 people, so about a quarter of the population of Gaza. But people also need water, sanitary products, medicial products, fuel, clothes, tents…
To provide adequate aid, we need to think in the terms of 3000-5000 trucks a day after 8 months of famine. Everything lower than that is lip services.
