Iran as a nuclear and regional threat that the Obama administration is too weak to confront. The topic is used as indirect political criticism.
Trump, still a non-political public figure, frames Iran as an immediate nuclear danger requiring strong action ('by any and all means necessary'). He criticizes Obama's lack of resolve and links Iran to Iraqi oil and American weakness. The tone is that of an outside commentator who knows better than those in power. Vocabulary is military and deterrence-focused.
