Atwa means "cease-fire" in Arabic
Atwa is also a song by System of a Down, found on their cd Toxicity, which was released in 2001.
In the song, Serj Tankian sings about the breakdown of relations between himself and another person. He has given up on trying to rectify the situation, as conveyed in the lines:
"You don’t care about how I feel
I don’t feel it any more"
Thus this cease-fire is not a happy event. Rather, Serj has sacrificed his feelings and called a cessation of hostilities between two hostile parties.
It should be noted that System of a Down is a band of Armenian heritage, but is often open to contributions from many cultures as shown in Serj's Serart album.
