Skirmish and Presidential tour

According to the Pentagon there has been a skirmish between Iranian and US forces in the Strait of Hormuz.
Apparently behind the harassment of US warships by Iranian Revolutionary Guards lies Iran's imperial ambitions. While, according to US leadership, the Iranian provocation is dangerous, the leadership in Teheran has downplayed the confrontation, calling it a case of routine identification. While this confrontation was taking place, President George W Bush was preparing for a tour of the Middle East starting in Israel. Following the reappraisal of the so-called Iranian nuclear threat by the National Intelligence Estimate, it is belived, that Bush will be seeking to shore up support ahead of a possible invasion of Iran.
