It wasn't just people on twitter saying it, it was Regev, in his Australian drawl stating that "Israel does not target hospitals". Seems a bit hollow now. I don't recall ever seeing the footage of Hamas command tunnels under the Al Shifa hospital, either. I suppose that now the Israelis have attacked it again and levelled it, we never will.
You have to wonder what the actual Israeli plan was at that point, and whether it bore any similarities to what the Israelis eventually did. What is certain is that whatever plan they have it won't work. There is no military solution to this conflict.
As an aside, it is fascinating to compare UK tv news coverage from the early part of the invasion to now. It is markedly different. Initially there was almost no Palestinian voice, very little attempt to provide one, and almost no footage of destruction on the ground. There was, in fact, wall to wall Israeli voice, often army spokespeople with regional British accents, and the ubiquitous Regev.
It's the opposite now. No Regev. No in person on camera Israeli spokesmen, loads of footage of Palestinian suffering and people on the ground.
