To quibble, I wouldn't say that Chomsky refutes the claims about the AIPAC lobby, which does have a strong influence. However, he does explain the ideological reasons why, aside from AIPAC pressure, the conservatives provide such overwhelming support of Israel.
DH: Chomsky argues that Israel has suffered terrible harm under US domination...
Chomsky mainly argues that Palestinians
have suffered terrible harm under US domination. Chomsky does suggest that Israelis would be better off if they agreed to a reasonable two-state solution. Still, the welfare of the Palestinians is the main concern of leftists like Chomsky.
It was interesting to read Chomsky's opinion about Israeli events of the last few years, such as the Hamas electoral victory or last year's invasion of Lebanon. Israel is a topic I'd like to become more familiar with, considering that I was brought up Jewish.
