Blockade on Gaza.
Bad arguments:"But Israel has a blockade on Gaza. They search everything being shipped in to Gaza."
Does any country have an obligation to turn a blind eye to weapons being shipped through its territory, especially when the weapons are going to be used against it?
The non-weapons goods did get through, right (before the Oct. 7 attack)? Israel did not prevent food and other goods from being shipped through its territory?
If it's a problem, ship through Egypt. Oh, wait, Egypt does the same thing? So it's not just an Israel issue.
