I am leery of getting into this, but it caught attention. Will try and pose some questions and responses briefly in as least inflammatory manner as possible:
Palestine is not a nation, and the news regularly is disingenuous by using terminology that assumes it is. Both Hamas, and the PNA, are at best, psuedo-governments, because as far as many international judgements go, it is an occupied territory rather than a sovereign nation. While not all people object for this reason, this is the reason why supporters can claim special treatment for the Palestinians in the public eye. Israel is a sovereign nation and official signatory to many treaties involving international law and war crimes. Palestine is not on the former and has muddled status on the latter. I'm all for being able to condemn both side when appropriate, but when Israel does something, legally, the international response can be more clear cut because no one can dispute Israel has responsibilities under the treaties it's signed. Similarly, referring to attacks on Israel as 'external' makes sense in a cultural sense, but the political and legal support of that matter can become muddled because of Gaza's political status.
Is it an occupied territory, a semi-autonomous zone, a nation, or an occupied nation? Depending on which way you answer this question, the Palestinian and Israeli responsibilities toward each other change drastically.
In addition : the claim that any nation would suffer severe hits to stability after refusing to respond to an attack, or loss of life by another aggressor is historically untrue. The United States has chosen not to respond militarily to quite a number of incidents in the past 50 years:

Not only did our failure to respond militarily to these events not doom our country's security, in several cases, defusing the situation was the overwhelmingly sane thing to do.
Thirdly. I, do not in any way celebrate Hamas's tactics, but as I think I saw Kara mention, the claim that all aggression has to stop from Gaza and things would be fine, seems... really shaky. Pragmatically, the Palestinians have next to no ability to exert political pressure on Israel in any other manner, and no guarantees of anything good happening for their side if they were to disarm. They'd have to remove their last remaining means of achieving local and international attention, on just the good faith that Israel would then deal with them, when the evidence so far to that indicates a less than optimistic picture of things. And even that situation is unbalanced:
You can say both sides have this issue of taking things on faith, but the difference is that if Israel was attacked in an overt fashion (i.e. the scenario painted that if not for the blockade, Palestinian forces could stream across the border into Israel, or the idea that an Israel that didn't power project would invite a massive attack by nearby Arab nations), not only can Israel expect some level of international assistance, they also arguably nowadays have such a powerful Military and Intelligence agency that they could win an extended fight like that. Iran is probably the only nation in the area that poses any threat to Israel, and Iran becoming involved would damn near guarantee the US would become involved militarily, and Iran is likely aware of this. Contrast that to the idea of Gaza taking things on faith and going completely disarmed. They'd be completely at the mercy of Israel, and the shaky hope that the only defense they'd have left would be the international community might help in time, something that seems less and less likely considering how little the international community has been willing to become involved in Syria or Ukraine.
I'm torn between condemning attacks on civilians while also understanding that many people in Gaza may have the perspective that they have no other option. Both sides are claiming that they don't want their people to be wiped out, yes, but one side has a dramatically higher risk of being wiped out than the other. Historically earlier in their history Israel might have been able to claim the reverse, but for right now, the Palestinians have a better claim to say their right to exist is in danger.
