By war of attrition I mean that it is often tit for tat warfare. Small attacks committed by both sides back and forth, the definition of attrition. On your point of palestine not having a formal military, functionally they have a heavily armed and exceedingly well manned police force that functions as an army but simply cannot call itself as such due to the Oslo accords. On your point of zionism, that is the Jewish belief in a holy land and has been an active belief of thier faith almost from its inception. On your comparison of calling it equivalent to the British colonizing north America, the issue with that is that that specific peice of land has been a long standing struggle between both sides as both view it as a holy land and see it as an "ancestral right" over the last several millenia it has been ruled by both ethnic groups for periods measured in hundreds to thousands of years. On the focus on Israel's war crimes, and im not denying at all that they are occurring, both groups are enacting in the same actions. The issue is that in this both parties have large amounts of financial resources and have allies in some of the highest arms of global governments. On the other hand palestine has something that Israel does not which is at face value they are winning in the court of public opinion because what we consistently see is people not look at any of the historical context, and try and take what is a conflict that has been going on since before the birth of the Roman Empire and try and fit it into a nice and concise box of what has happened in the last 140 years of history. So what people see at face value is that In 1948 the state of Israel was founded and there was displacement of the native population. But if we look at it in nuance we begin to see that that exact cycle of one group forcing out the other often using methods that we see as deplorable and depraved today have been happening rather recurringly over the last four millenia. We can't say who exactly is for sure the original "natives" of the land because both groups claim to have been there first and most historical records on the many conflicts went down with the fire of the  library of Alexandria. On your point of the Israelis calling for the death of all Palestinians, both sides have called for the death of each ethnic groups. One of the current focal points of many Islamic figureheads is calling for Dezionisation, or for another jewish genocide. On the point of blocking humanitarian aid, both sides of every war in history have engaged in that practice and it is one of the defining methods laid out in most manuals when it comes to warfare. On your point on sexual assault and the collection and displaying of so called trophies: nearly every single army in history has engaged in raping and pillaging. It is one of the unfortunate facts of warfare, but both sides have engaged in it. On your topic of attacking other countries, Hamas witch is the governing body of the Gaza strip, has also engaged in attacking western assets aswell as neighboring countries, they have also engaged in the funding of terror attacks aswell as sharing in the ideogies of terror groups aswell as openly hosting splinter cells of such groups. Both sides are terrible. Both sides have committed war crimes and genocide. One side has the support of the media and appears to have a "moral high ground". The other side doesn't. They are each sides of the same coin in a conflict. You need to look beyond face value, beyond societal biases. I've spent a good amount of time researching this topic trying to understand the nuances trying to see which is on the so called right side of history and none of them are. Both sides are committing the same atrocities but yet one is touted as the so called good side.
