Is this primary an attempt by the Hamas leadership to lever themselves into the 'leadership of the Palestinian Nation role' with a secondary intent of trying to slow down the (inevitable?) recognition of Israel by Saudi Arabia?
As with all political elites throughout history Hamas will send their young men (and it will be mostly men) to fight and die whilst they keep themselves and their sons far (in this case 100s or miles in air conditioned comfort third countries, Qatar mostly) away from the immediate risk.
The soldiers sent out from Gazza will be young and poor, some will be heroes, a few psychopaths who will take pleasure in the killings, but most just young men with no future who will bravely go and do what they they see to be their duty for their country and will lose their lives.
Similar to the Israeli men and women who will also do their duty to protect their neighbours in war of occupation prolonged and stoked by the bastard offshoot of western right wing popularism by Netanyahu.
The only thing that can be said with any certainty is that Netanyahu and Haniyeh are both cunts with too much blood on their hands
