This is not a pro-Israeli or pro-Palestinian post, this is a pro-humanitarian post. I am not taking a party and what I write here is just a practical concern on people, whoever they are. In the current situation, medical facilities in Gaza cannot deliver the services that people who are ill or injured require. Israel is unlikely to allow a flow of medical supplies since these could potentially be used by Hamas (I am not here to judge how good this argument is).
There is however no reason why hospital ships could not be used to care for children, pregnant women, old people and others that require special attention. Even men and women in general.
In situations like this, it's the sole responsibility of the US and sometimes joined by the EU to support situations like this, they can make mobilization to help in this critical condition with every necessary support they needed and this doesn't have to come with conditions attached as long as there's a circular memorandum of understanding for that, alot of people were suffering for this already and this is human lives we are talking about and not animals or alliens.
