Sheesh, where to start?!
Clark was a perfumed prince in the military who uniformly annoyed, angered, and was opposed by everyone in the ranks below, at, and above his pay grade level...save those few who like Rhodes Scholars, megalomaniacs, and politically-connected machiavellan ministers.
In his zest to lead NATO headfirst into war against Serbia over Kosovo 4 years ago, Clark fully ignored the UN, refused to consider UN inspectors to verify the claims of "mass graves" and "genocide," as well as bombed civilian TV stations/studios while they were on the air (and he also bombed civilian bridges while human shields were visibly present on them). But besides ordering attacks on civilian targets, Clark also insured that foreign diplomatic targets, such as the Chinese Embassy, were also hit. If it could make America look bad, Clark pretty well ordered it.
"I'll not start the Third World War for you," said British General Mike Jackson as he DISOBEYED Clark's direct order to open fire on Russian paratroopers who had just landed at the Pristina airport in Serbia in 1999.
Clark was then fired from NATO as well as fired from the U.S. military. He returned to Arkansas where he received jobs from friends of Bill Clinton. Staffers on Clark's campaign almost all have experience campaigning and fund-raising for former President Clinton, and this is why people like Eli Broad can say that they just "know" that the Clinton's favor Clark even though there has been no announcement by the Clinton's regarding who they favor/endorse.
Which means that Hillary is still considering Clark, among others, to be the annointed one to select her as the Democratic Party VP candidate in 2004...
