I was born and raised in Spain, and now live in the US. In my experience, the coverage of news about Israel in the US and Spain are about as different as black and white. What you describe about The Guardian seems like normal coverage in Spain.

The experience mase me understand that, in practice, all sources have major amounts of spin where you might not expect it, and that it is very difficult to figure out which spin, if any, is closer to reality. It's not about fake news, but about how wide the journalist's sources are, and how much did they care about digging for what is real.
