Well don't you know? In the worldview of certain people there are major powers and all other countries have to lick their boots or perish. Whether that major power is the US, China or Russia depends on the particulars, but a surprising amount of people hold that opinion, probably without even being aware of it.
What made me realize that was the people who jumped in defense of Russia, because the people of Ukraine aren't allowed to join EU or NATO, because for some reason the people of a sovereign country have to respect the will of a paranoid neighbour, who wants to keep a "buffer zone" for completely irrational reasons. Who would have invaded? The Belgians?
And I mention the Ukraine because they will surely think:"We should have kept those nukes". And wo can blame them, one of the powers at the Budapest memorandum attacked them while the other two reluctantly sent weapons. So with nukes they would have had better cards.
After this episode the Iran is probably more motivated than ever to get nukes. And who can blame them, they had a good deal with the west, Trump comes along tears it up, can't deal with the consequences of tearing it up, Israel is so comfy the US will dance to its tune they attack and surely the clowns dance. Lesson: don't make deals, these idiots just listen to raw power.
Who loses? Everybody.
