First panel: I agree with the aspiration to avoid violence but allow for circumstances like self-defense or defense of a vulnerable party.
Second panel: I do agree we shouldn't give them weapons, at the least not lethal weapons, certainly not military-grade weapons.
Third panel: If you want to be capable of preserving your national sovereignty, having a military is required, therefore justified in that context.
Fourth panel: While the two previous questions logically follow from the position stated in the first panel, the last question makes no sense and is a complete non-sequitur from the stated position. [i.e. "Violence is never a solution" --> "oh, so do you mean it's a solution in this one case? !? !" <--non-sequitur]
