If it is a potentially impeachable offense to lie about an affair, what would you call knowingly presenting false, unreliable information to your country in order to provide a pretext for a war against another country? No matter whether you feel a war on Iraq was justifiable, there is no justification for a president to knowingly misrepresent the truth in such a manner.
Impeach now?! Sure... why not.
