1:15 PM PT -- War is over. Snoop just apologized.
Snoop Dogg chose the nuclear option in his war with Iggy Azalea ... calling her a "c**t" and warning her "n**ga" to put her in check!
Snoop posted the video late Tuesday night ... staring into the camera as he said, "You're f**king with the wrong n**ga! And your n**ga betta check you before I do."
There's more, and the tone of this is definitely not playful anymore.
Snoop may have escalated things because Iggy finally shot back on Tuesday by posting a pic of snoop with the caption ... "When your drug addict aunt gets clean."
Snoop captioned his post ... "Last one until she speak now shut da F** up ubitchu."
We doubt it.
