I'm not claiming that a few sanctions end a conflict by themselves. This issue isn't black and white - and also, sanctions typically work on a scale of years, not days.
You can bet that all the sanctions in the past contributed to the current destabilization of the iranian regime.

Just like russia claimed they "don't care" about sanctions. Riiiight. Autocrats can't admit that the sanctions hurt, but their effect is pretty easy to show.
They care a whole lot. >

Not really, otherwise this war would be over and NK wouldn't have nukes and Iran would be willing to negotiate.  
The leaders who the sanctions are supposed to affect have entirely alternate financial institutions that bypass sanctions altogether. The smart ones at least.
