Refuah shlema! However it is the obligation of every top government and military person in Israel to be healthy and that means not overweight! This should be a public issue and a policy. .Be fit not fat!
Like Ariel Sharon, Meir Dagan who was critically ill Belarus I think, Ehud Barak, Lieberman and others Netanyahu's weight threatens his health. of course we are all concerned for him and wish speedy recovery, good health and a long life. However, all of the above people who hold or held top positions in government have an obligation, both security-wise and morally, to be lean and fit. Peres is pretty healthy at 90 because he looks after himself - his son-in-law is a doctor and I'm sure that helps.
