It wasn't legal then and it's still not legal.
The UN, F***** Up as it is, still has a fig leaf of a charter to hide behind as they try ineffectually to play at soldiers. On what bases does the NATO organization claim authority to interfere in the internal affairs of sovereign nations?

Perceived threat.
Ask Klintoon. He refused to act until the NATO pact was changed, remember? Hillary (along with the rest of EU) harrassed him for at least a year to bomb until he acquiesced. Then only with "no U.S. lives lost". Bombing from high altitude. NATO would not have acted without the Toon's first step.
