Kucinich is right. From a strictly legal standpoint, Obama's ordering US troops to fire on troops of a sovereign nation which did not attack the US is an impeachable offense. It is an act of war, and only Congress can authorize an act of war.

If Obama is impeached, Joe Biden would become President, which IMHO would not be a disaster. He would get to name a Vice President, which, AFAIK, could be Obama. :-)

I'm surprised Kucinich would not draw up articles of impeachment himself: he knows Obama would be acquitted. After all, impeachment requires a unanimous vote.
