> The rational move for Iran to prevent itself from being bullied is to have nukes like North Korea

North Korea invaded South Korea, stole a US Navy ship (the Pueblo, which they still proudly exhibit), dug large infiltration tunnels under the DMZ, kidnapped hundreds, or even thousands people from SK (and Japan, to a lesser extent), and have assassinated, or attempted to assassinate, multiple SK heads of state, and perpetrated acts of terror like: https://en.wikipedia.org/wiki/Korean_Air_Flight_858

What did the US or SK do to them before their nuclear program that constituted "bullying?"
