When your enemy explicitly calls for the death of all your citizens and this idea is shared among a majority of their population then it is both logical and fair to do the same to them first.
Calling for , and being able to execute such a threat are two different things . If Hamas had the ability to do it ,I'd say your point is valid , but just some fucking crazy guys screaming , Ehhh, kinda like Panama calling for the destruction of the US.
