I wish people would get a grip. The senior President Bush is from the old school .. of diplo-speak, being friendly with your adversaries.
That said .. please also remember that even though Bill Clinton was impeached - he's still a former president. I firmly believe this is about THE OFFICE OF THE PRESIDENCY - and not anything personal. In fact, we need to leave anything personal out of it. It's a restoration of the status of THE OFFICE.
Bill Clinton has sullied THE OFFICE - therefore, the Sr. Bush is trying to remove the smear from THE OFFICE - not the person of Clinton. Actually, I think this is a good thing. Clinton needs to learn some manners - and Clinton needs to learn what his obligations are regarding THE OFFICE OF THE PRESIDENCY.
I know, I know .. it's hard to separate the two (personal and office) - but we would be less frustrated with Bill and George HW's relationship if we would try to understand the real goal - restoration of respect for the office and not Clinton's personal reputation.
