Of course the war was one-sided. You can’t genuinely believe it wasn’t?
On the one hand, you have tinpot paramilitary groups firing off home-made missiles. On the other, you have one of the strongest and most experienced military forces in the world, with overwhelming superiority in skill, arms and firepower.
There’s a clear difference between missiles cobbled together from whatever construction materials are available and laser-guided precision air strikes.
This difference is also made clear by how few Palestinian missile attacks on Israel there have been since the first couple of months of the war - their infrastructure has been destroyed.
Additionally, I don’t get the point of bewailing what might have happened if the Iron Dome didn’t exist. It exists. It’s existed for years. Israelis know it exists. Palestinians know it exists. Palestinian armed groups fire their missiles in the knowledge that the vast majority headed for populated areas will get shot down. It’s far more about the psychological and disruptive impact, which I absolutely do not deny - while also recognising that the trauma endured by Palestinians, with no Iron Dome, no shelters, and facing far more dangerous missile attacks, is of a far greater magnitude.
