People will claim it is, but it really isn't. Honestly, you'll read a lot of biased answers here.
The safest bet is to condemn the rape, murder and torture of civilians, but accept that there are no 'good' guys in this conflict.
To give you an idea:
You'll read a lot of comments about how Israelis stole land from the Palestinian Arabs. But Palestinains also stole land from Palestinian Jews.
Many middle-eastern countries had significant Jewish populations before that, but almost all were forced to flee to Israel. Something like a third of Israelis are 'Arab' Jews or Mizrahi as the prefer to be called. They're not 'foreign invaders'. They're (the family of) locals or refugees from neighbouring countries.
Hamas are horrible, and what the last few days have been deplorable, but arguably Israel helped create them.
Also, recent right-wing Israeli governments have consistently undermined any hope of a peace deal, meaning there's no real alternative for Palestinians.
But, back in 2000 Israel did offer far reaching concessions to the Palestinians, so much so that IRC the Saudi ambassador said it would be a crime not to accept them or at least continue negotiating. But Arafat, the Palestinian leader at the time, did just that.
Also, neighbouring Arab countries claim to support Palestine, but often only on paper. When they accepted Palestinian refugees this caused them huge issues. For example in Lebanon:

https://en.wikipedia.org/wiki/Karantina_massacre
Also, a lot of arab nationalist groups, including Palestinian ones, are virulently anti-semitic and have actual historical ties to the nazis who supported them in their fight against the colonial powers (Britain, France, etc.):

But then the current Israeli government contains ultra-nationalists. One of the ministers once belonged to a banned far right terrorist organisation, labeled as such by the US and Israel. They were openly racist and supported terrorist attacks against Palestinians.
If you re-read my comment, you'll note I said that something like a third of Israelis are (originally from) from the middle-east or arab countries.

3.2 million / 9.5 million = 33.7%.
Wikipedia:
So 33% from the MENA.
15% Soviet.
Ashkenazi(mainly Europe): 2.8 million / 9.5 = 29.4%
IRC the rest are non-Jews.
That took far too long to google, which is why most people debating the whole conflict simply don't bother. Why would they when they've already come to a conclusion and chosen a side? Why let the facts get in the way?
Honestly, this is why I'd rather swim in a septic tank, than spend too long debating the whole thing.
