a) What "other measures"?
b) I don’t support current Israeli actions on the West Bank or in Gaza but talk about the Gaza population being "close to being wiped out" is absolute blatant nonsense. The UN estimates the population of Gaza at about 2.1 million, and Hamas say about 40,000 have been killed. That's about 2%. Terrible, but not "close to being wiped out".
You’re right that Israel has the power to do it though - if they really wanted to, they could have done it months ago. So obviously they don’t want to.
c) Your airy dismissal of, and unconcern about, Hamas's murderous racism is sickening. I wonder whether you would be so uninterested about blatant racism against against any other race.
