I'm sure airdrops have their place, but they aren't a primary means of feeding 2.2 million hungry people, (over 500,000 of which are at the most severe level of starvation according to the UN). Yesterday's drop was reported as 38,000 meals, so enough (assuming every meal makes it to the right place) to feed 7.6% of those 500k most desperate people one single meal and meaningless to the other 92.4% of victims.
If the US negotiations result in several hundred trucks a day being allowed in, about 3x more than the most they've let in since Oct 7th, then I'll believe the airdrops were a good-faith start to aid. Otherwise it's undeniably true that this is just bad theater that a lot of folks aren't going to fall for. I'm not even sure how much it will help politically - those who are going to vote for Biden regardless of aid don't need to be swayed. His critics, on the other hand, aren't going to be convinced when over 90% of Palestinians keep on starving and he gets repeatedly called out for a weak attempt at relief.
Also, even aid does nothing to address the Israeli actions that are creating this crisis in the first place. When talking about American racism, Malcom X said, "If you stick a knife in my back nine inches and pull it out six inches, there's no progress. If you pull it all the way out that's not progress. Progress is healing the wound that the blow made. And they haven't even pulled the knife out much less heal the wound. They won't even admit the knife is there."
