After all this time has passed, I don't know what the state of the resistance is in Gaza itself. It's not good though The cranes are also likely heavily guarded

this is the reason they support Israel

they don't want Israelis (and also to a lesser extend Jews) in their countries

From the half life fandom wiki:

The Seven Hour War was a brief but decisive confrontation between the Combine and the governments of Earth, ultimately leading to a large human death toll and the surrender of the planet in less than seven hours. The victorious Combine began their occupation shortly after.

This doesn't claim that they are literally based on the IDF, but being the occupiers would make the combine the IOF in any analogy between the two. I've been meaning to replay half life since it's been ages for me so I'll be paying attention to whether this holds up when I do.

From what I remember though, it seems believable. It's obviously not a perfect 1:1 fictional recreation, but thinking about the world of half life the similarities are striking. Humanity was facing total annihilation by an unbelievably cruel and powerful force that they couldn't resist under total war. Their total surrender saved them, but resulted in an oppressive occupation where the humans who were willing to accept this surrender and collaborate with the combine were the only ones allowed to have political power, and that power could only be wielded over other humans, not the combine. Thus the indigenous population of earth was subjected to apartheid. The combine came from a vast empire, and their rule and power is precarious because it depends on connection and support from the greater empire. Then there's the gameplay, where the resistance need to stay hidden and use urban guerilla tactics in a concrete jungle of a city that they are confined to. It does sound like how I'd imagine Gaza before october 7th.

I remember this being somewhat implied in Raising the Bar
