They will still be stopped, they need to check for weapons and explosives.
Israel cannot afford to let explosives disguised as bags of sugar and the like into Gaza.
It has happened before.
BTW it is legal to stop a ship in international waters, if you have good reason to suspect they are smuggling weapons or explosives.
So it isn't technically piracy, as someone said it is, earlier.
I agree that things need to improve, but you need less intransigence on BOTH sides for any peace plan to work.
