> Ukrainians spontaneously united against the actions of President Viktor Yanukovych after his government refused to sign the Association Agreement with the European Union, which had taken seven years to negotiate, due to pressure from Russia.

If the Ukrainians spent 7 years wanting to get closer to the west and then as you say "[Yanukovych] changed his mind". I think it's easy to see the populace wanting to oust this leader and that the following leader would be pro western, like the leaders in the seven prior years.
