thank you to all who answered.
Aleksey, you are right that aikido has ukemi but what they were discribing in the newspaper article was that they teach attacks FOR attacking. Aikido does not start a fight but of course you learn how to deliver it. Anyway, I think the writer got it wrong, I don't think they learn to attack without being attacked (by the link that was offered).
Ze'ev, thank you for the link, it's very helpful.
Ian, if I find a link in english, I'll let you know. It's a but long to rewrite.
Thank you all.
