@davidho because they demonstrate that only one of the conflict sides should stop they actions and not the other... #BringThemHomeNow maybe
And this is just an possible explanation, not an excuse for an actions in this conflict
About the two sides that you're mentioning - I'm assuming they are, at their core, Israel and Hamas. They are not independent. They are not two different countries that both want control over the same thing.
In Israel's case, Hamas was born because of the Israeli occupation. (It was also aided by Israel/Netanyahu, but I'll ignore this for now). If Hamas stops, Israel will continue what it has done for the past 70+ years. If Israel stops, Hamas will cease to exist. Extremist groups have power only if the general population is desperate (I would love if you can find a counter example to this, I cannot right now).
Regarding the current conflict, all the ceasefire talks resolved to this: Hamas asks for a two-state solution, Israel refuses a two-state solution. There is a single side that can and has to give in here.
@arh sorry but if the situation was not so tragic, it would be the joke of the day. Hamas what's a two-state solution?
And just to make it clear, I'm not agreeing with what the IDF is doing (also in important specification, as they are massive criticism in Israel against what is happening in Gaza)
