Again I apologise to ABers and Mrs Gillard for wrongly attributing that fine speech to her.I did find that out this morning and on one site it suggested,also erroneously,that it was also attributed to a former Australian PM three terms and ten years prior to her premiership.
The original text,as shown by JTH's link, is apparently attributed to an ex US veteran who made a very similar speech after 9/11.
Same usual suspects, same theme (terrorism ) different country.
