The statue of Lenin can be viewed in a variety of ways.  I like to look at it as a trophy of conquest.  We won.  The commie bogey man is no more.  See?  This symbol of communist authority, the cult of personality, it's here, powerless, a reminder of a sad chapter in history.  Sayonara mother fucker.
