In your view, would the USA, Japan, or South Korea have been justified in striking North Korea’s nuclear program at any point before or after their development of nuclear weapons? If so, when?
Note that North Korea has repeatedly threatened to re-unify the country by force.
I'm not really aware of the circumstances of that so hard to say. I'm more aware of Iran because of recent events. I'd doubt it would have been legal and if that was the case I would not see it as justified.
I'm not aware of any illegal wars this century that I do see as justified.
I personally don't believe any country should have nuclear weapons.
I think it makes sense to be against military action in general, though it’s a much more persuasive position in a safe western country than Israel, South Korea, or Ukraine.
I also think you’d be well-served to learn a bit more about the history of nuclear proliferation if you wish to argue your points effectively.
When it comes to nuclear weapons I'm located within 50 miles of a nuclear military base so it is something I am keenly aware of.
I don't see Israel making itself or others safer by pursuing illegal wars. The reverse is Ukraine which is the recipient of an illegal war.
There are very few actions that make the world less safe than this sort of reckless and unjustified action. It just reinforces to me why they are illegal.
More knowledge and context always help of course, but I do see a lot of rhetoric being put forward on this subject. My replies may be imperfect but I do think they help with balance. Is there a particular point you believe I should be considering?
