The reason Bolton has been getting so much "page/web/face time is that John has never met a potential US military conflict he hasn't just loved; particularly when that conflict may well pit the US against any one of Israel's many existential threat, like Iraq, and now... Iran.
Of course, John's never seen a day of warfare up close in his life; he's an attorney whose bio indicates a series of jobs in and around Washington DC.
Most people who have actually seen combat, up close and personal, are generally not so deeply in love with war as the ultimate solution for everything as Bolton appears to be.
The drumbeats for war against Iran are beating faster and faster, with Obama and Gates haven been given their marching orders from Tel Aviv recently in a series of meetings there and in Washington.
Obama has indicated now that Iran has only until the end of September to acquiesce to his demands. After that time frame, we could well see an "October Surprise" in the form of an Israeli-led/US-supported attack against Iran.
