Iran Nuclear Program: Israel Pressured Not To Strike Iran Alone By Crispian Balmer JERUSALEM, Aug 31 (Reuters) - Israel is facing growing international pressure not to attack Iran unilaterally, with the United States in particular making clear its firm opposition to any such strike. Recent rhetoric by Israeli leaders that time is running out to halt Iran's contested nuclear programme has raised concern that military action might be imminent, despite repeated calls from abroad to give sanctions and diplomacy more time to work. The U.S. Chairman of the Joint Chiefs of Staff, General Martin Dempsey, has always cautioned against a go-it-alone approach, but he appeared to up the ante this week by saying Washington did not want to be blamed for any Israeli initiative. "I don't want to be complicit if they (Israel) choose to do it," Dempsey was quoted as saying by Britain's Guardian newspaper on Friday, suggesting that he would view an Israeli attack as reprehensible or illegal. He went on to repeat that although Israel could delay Iran's nuclear project, it would not destroy it. He said that unilateral action might unravel a strong international coalition that has applied progressively stiff sanctions on Iran.
