For some the idea of Sharon lying in his current listless state raises difficult questions about whether or not he should be kept alive.
"It's up to the family," said Gissen. "He is still alive. If you stop feeding him, he will starve to death. That's against every Jewish law. There is still the slightest chance he may improve, although it's very unlikely. It's up to the family."
Gissen clearly misses his old boss. He said Sharon was one of the last "founding fathers of Israel," part of the generation of soldiers and politicians who helped establish the Jewish state in the 1940s. Despite their decades-long relationship, Gissen has chosen not to visit Sharon's hospital room.
"I don't want to see him in this condition. It's very sad, it's tragic. I don't believe he himself would ever have wanted to end up like this."
