Is not one of the State's jobs to defend its citizens?
How is a State (Israel, Iran, Germany, the US, etc, etc, etc) supposed to defend its citizens - one of the jobs its citizens pay taxes for - without the use of weaponry?
States which do not have a strong (or overwhelming?) military industrial complex end up in situations like Ukraine is in now - under attack by other States (Russia, in this case) simply because a leader wants better ports to launch more attacks from in order to engage in World Domination (my impression, not necessarily fact).
