The valid conclusion about these political phenomena could be that the very strong anti-Vietnam war movement of the American and world's people definitely had an impact on Johnson not running and also somewhat on Nixon (as well as Watergate) and there may have been a backlash against the war mongering of George HW Bush in Iraq and also the brutal invasion of Panama.
The correct answer to this question is King Leopold II. The American explorer Henry Morton Stanley staked claims along the Congo River in Africa on behalf of King Leopold II. Thank you for posting your question.
