Please refrain from vandalism/political edits in OSM.     
All the six Arab countries in the Arabian Gulf use the name Arabian Gulf, so Iraq being one of them has the name on it's border line w306443658. You changed that to "persian Gulf" which is not used by Iraq, only used by Iran, the sole country that uses it in the gulf. So please do not force a name to a country that do not use it.        
You also fiddled up with Iraq's maritime borders overlooking the Gulf making them lesser and enlarged Iran's maritime borders and exceeded them on the Iraqi maritime borders. This is pure vandalism and will be reverted too.    
Again, refrain from such edits.      
Bye.
