The pier is pure political show biz. Not helping children starving NOW. The US provides billions of foreign aid to Egypt, Israel and Jordan, countries bordering Gaza. Make them an offer they can’t refuse: allow your territory to be used as a staging area to bring the aid into Gaza or we stop propping you up.
Since the US is also the UN’s sugar daddy, how hard would it be to convince the organization to provide security for moving and distributing the food NOW?
