He recently said the Armenian Genocide didn't happen and was a pretty strong advocate for the 2006 Lebanon war.
I never knew that Peres said the first part. That reduces my opinion of him, even though it wasn't that high to begin with since as PM of Israel he almost never responded to terrorism (even though he was supposed to, since protecting your own citizens is more important than always pleasing the U.S.). I agree with Peres on the Lebanon War, though, since Hezbollah needed to have the crap bombed out of them so that they would stop firing rockets into Israel and stop killing innocent Israeli civilians.
