Is there a noticeable difference between:

A) A grateful population cheering their liberators and tearing down the symbols of their hated oppresors

and

B) A population seeing which way the wind is blowing and ingratiating themselves with their new conquerors?

I'm not suggesting B is happening instead of A. I just can't think of a way to differentiate the two.

UPDATE: Okay, they're starting to yell at us to get out of their country. That is not the act of a brown-nosing population. I guess I can accept the gratitude as sincere now.
