Against the Zionist Enemy or just more Arab games of Aliens v Predator?

Solomonia reports that the Al-Aqsa Martyr Brigades (one of the implausible deniability wings of Mahmoud Abbas' Fatah in the Gaza strip are forgoing buying food for their kids so they can spend the money on weapons.

The reason? The official one from Fatah is

the renewal of the threats emanating from the Zionist military establishment to carry out a new attack on the Gaza Strip... the Al-Aqsa Martyrs Brigades... warned of a harsh and painful response that the occupation state is not expecting.

Of Course, the same Fatah website notes that

many of the Brigades' Jihad (Islamic War) fighters purchase weapons rather than food for their children, and many of them have even sold their wives' gold [jewelry] in order to obtain weapons, since the Hamas forces have confiscated the Brigades' members' weapons

What's the odds that the whole "threats emanating from the Zionist military establishment" is just a pretense to cover Fatah purchasing weapons to be ready for the next go-round with Hamas for control of Gaza?

After all, it was according to the article Hamas that confiscated their weapons from them the first time.
