Iran's supreme leader claims that America's attacks were unsuccessful

Iran's Supreme Leader, Ayatollah Ali Khamenei, has made clear that the US has "gained nothing" by striking his country's nuclear facilities. According to Khamenei, America has not had 'any meaningful success' in its efforts to halt Iran's nuclear program He called Iran's strike on the US airbase in Qatar a massive 'blow'. Khamenei remarked this at a time when the US has frequently stated that its strike on Iran's nuclear sites has resulted in significant casualties. At the same time, the US Defense Minister claims that information input received by America and Israel indicates that the attack has pushed Iran's nuclear program back several years.
