Israel is full blocking aid trucks which they can easily inspect. Even the few they were originally letting through were attacked to scare off NGOs and the UN. Their demand to search the packages is just a ruse they can use to halt the flow.
There is a ridiculously low chance Hamas has been successful in smuggling anything related to weapons for the past 6 months via the aid.
Meanwhile the remaining Gazans are starving to death because Israel has already decided all Palestinians are Hamas and must be eradicated from the area.
The USA could at anytime use its insane MIC leverage to force Israel to let aid in, but they won’t because they see Israel as a prime ally.
