[source] John McCain, who has harshly criticized the idea of sitting down with dictators without pre-conditions, appears to have done just that. In 1985, McCain traveled to Chile for a friendly meeting with Chile's military ruler, General Augusto Pinochet, one of the world's most notorious violators of human rights credited with killing more than 3,000 civilians and jailing tens of thousands of others.
[source] In 1987, John McCain cast several votes in an attempt to force the Reagan administration to meet with RENAMO, a guerrilla organization in Mozambique that State Department officials at the time described as a "terrorist group," without requiring that the group meet any preconditions.
McCain is the candidate of change, because he is always changing his views. He's like a merry-go-round. Just wait awhile and he will be all the way on the other side and heading in the opposite direction.
Of course, there's a very long list of issues where he has done a 180° turn.
