Speaking of Style Guides

Apropos yesterday's style guide discussion, The New York Observer took a look yesterday at
West Bank and Gaza Strip. Territories under Israeli control from 1967 onward. 'The territories' is acceptable on second reference, as are Judea or Samaria for the Southern and Northern regions of the West Bank. Avoid the phrase 'occupied territories.'
Unfortunately, the Observer didn't excerpt the Sun's rationale for its habit of using the phrase "Palestinian Arabs" instead of "Palestinians."
