Corrections and clarifications

Yesterday's cartoon on page 29 (Comment) portrayed Israeli military action in Lebanon in the form of a mailed fist with Stars of David as knuckle-dusters. By failing to identify them in a specifically Israeli form - such as in the colours of the flag - the point the cartoon was making might have been interpreted as implicating Judaism rather than the Israeli government in the present conflict. That was not the intention, and we are sorry if anyone saw it that way.
Gee, just like the Neturei Karta. We love Jews; we just can't f*****g stand those "Zionists".
