short attacks us over tsunami aid former cabinet minister clare short has criticised the us-led tsunami aid coalition  saying the un should be leading efforts.  president bush has announced that an alliance of the us  india  australia and japan will co-ordinate a humanitarian drive. but ms short said the effect of the parallel coalition would be to undermine the un. she said only the un had the  moral authority  to lead the relief work. ms short resigned as international development secretary over the iraq war.  i think this initiative from america to set up four countries claiming to co-ordinate sounds like yet another attempt to undermine the un when it is the best system we have got and the one that needs building up   she said.  only really the un can do that job   she told bbc radio four s pm programme.  it is the only body that has the moral authority. but it can only do it well if it is backed up by the authority of the great powers.  ms short said the countries involved could not boast good records on their response to major disasters. the us was  very bad at coordinating with anyone  and india had its own problems  ms short said.  i don t know what that is about but it sounds very much  i am afraid  like the us trying to have a separate operation and not work with the rest of the world through the un system   she added.
