According to the story, this survey was initiated because of pressure on Hamas in Gaza, as well as fear that a political solution will arise that would exclude Hamas.
One paragraph of the story is telling:
The survey results suggest that the current situation is difficult and harsh, particularly in terms of attrition of the capabilities of Hamas. The movement also fears that people's priorities are changing towards improving conditions of life at the expense of national aspirations, and this is expected to increase pressure in the next phase of movement to allow for the ascendancy of the Fatah movement. "The bolded part needs to be emphasized to the world: Hamas (and, historically, many Palestinian and other Arab leaders) are so insecure in the nationalism of Palestinian Arabs that they want to keep them in a misery-induced unity. To them, happy Palestinian Arabs will no longer identify as "Palestinian" and will not be useful for their own political and terrorist aspirations.
This next paragraph is more difficult to understand in autotranslation, but I believe my restatement is accurate. If someone who knows Arabic could check it, I would appreciate it and correct it if necessary.
(PPNA is very anti-Hamas and occasionally errs, but most of their stories turn out to be accurate.)
The study shows that that Hamas believes it is capable in the foreseeable future to bring about major breakthroughs in the field of conflict, and thus be able to primarily address more [military] steadfastness and stability, and it is betting on time waiting for [improvement of] the quality of weapons [autotrans: "variables"] [manufactured] within the country or [smuggled from] abroad.
