Olivier Martinez: I Will Not Start a Custody War With Halle

Olivier Martinez will not wage a custody war with Halle Berry, sources connected with the couple tell TMZ ... because he does not want to go through with the savagery he witnessed between Halle and Gabriel Aubry.

We're told Olivier was horrified by the bitterness between Halle and Gabriel, and the toll it took on their daughter Nahla. He's satisfied with joint custody of their 2-year-old son, Maceo, and we're told Halle is also down with that.

We're also told Olivier has no intention of moving to France and starting a Kelly Rutherford/Daniel Giersch type international war.

It's lucky for Halle, because she wanted to move Nahla to France, and tried unsuccessfully to convince a judge it was a better place to raise kids than the U.S.
