The source said that this would explain why Israel did not hit any Hamas sites during the fighting earlier this month.
Of course, the IDF did target Hamas sites:
The article goes on to say that Fatah has been quietly accusing Hamas of giving Israel information about the PRC leader, Zuhair al Qaisi, so Israel could assassinate him before his planned terror attack, which would have been far more costly for Gaza. This explains, according to Fatah, why Hamas did not join in the fighting.
Whenever Fatah insults Hamas, it is never because Hamas embraces terror. It is always because Hamas is supposedly too pro-Israel.
Which tells you all you need to know about how "moderate" Mahmoud Abbas' party is.
