"Imagine lying to the entire planet and starting an illegal war and occupation
killing a million Iraqis"
The "Million dead Iraqis" meme is itself a lie, and doesn't take into account the fact that the overwhelming majority of actual civilian deaths in the Iraq War were committed not by American troops, but by the Iraqi insurgents deliberately targeting civilian areas (i.e. suicide- bombings in marketplaces).
Imagine lying to the whole planet and fudging temperature data for years and telling everyone that the earth will freeze by 1980 burn up by 1988 1992 1996 2001 2010 2015...and there are people that still listen to Al Gore today.
Or be annihilated by hurricanes by those dates, as a direct consequence of EEEEVIL humans driving non- hybrid cars and eating meat. Or telling everyone, as fellow climate change hoaxer Paul Ehrlich once did, that "England will not exist in the year 2000."
