It is obvious

Anybody who pretends to engage in Palestinian advocacy, or who trade in Palestinian affairs with Gulf regimes, and who supports Abu Mazen and or Salam Fayyad is a timid supporter of Israeli occupation.  Supporting Abu Mazen or Fayyad is like supporting Antoine Lahd and claiming to seek Lebanon's liberation from Israeli occupation.  There is no legal or political or methodological difference between Lahd and Abu Mazen and Fayyad.
