Agreed and point well received.
Just want to point out that the situation in NK is different than Turkey because, as we all know, it's a nuclear power in close proximity to a treaty ally.
With Iran... well, we can see the ridiculous predicament that we are in today because of the unilateral actions of one party over a treaty agreed to by 7 signatories. I would not rule out direct military intervention and regime change in the near future there just yet (at massive cost of human life). The world has seen one too many times what happens when nations disobey the global hegemon.
It may indeed seem silly and tin-foil hat-ish, but there are many ways of forcing regime change without overtly declaring war. Coup d'états, spontaneously occurring uprisings, etc.
Not to indulge in the paranoia of world leaders too much, but Erdogan famously survived his 2016 coup which he claims to have been backed by the CIA [1]. The Philippines' Duterte has mentioned in several interviews (in a non-sarcastic way) his fear of being assassinated by the CIA after his pivot towards China [2]. The truth is that geopolitics is probably simultaneously more boring and more full of intrigue than we can imagine.
