Really nice thought but the major problem is getting the aid inside Palestine as it like an open air prison I am talking about Gaza Strip as the aid should either enter through Egypt or Israel but both of them are inhumane and there are generous donors who has done enough but the ground challenges are getting the aid delivered.
The cycle goes like israel attacks Palestine the we see aid being sent to them meanwhile there are thousands who are killed and maimed. The real help they need is stoppage of this genocidal campaign and a permanent solution to this occupation else aid just means that feed them and kill.
Since it is not possible to cross Israel to reach Palestine, it is possible to consider an alternative route but to reach Palestine with relief. If we can't help directly, then we can collect some amount of donation and transfer that donation to any trusted foundation, they will definitely deliver the relief to the Palestinians on our behalf.
