No, Obama did not fulfill his objectives, because the country is not yet completely socialist. If you read Obama's books, it is quite clear that Obama thinks America owes a debt to other countries, and that America should implement complete redistribution of wealth. Because he has failed to make all of these things happen, he has not fulfilled his objectives.
Like most presidents he promised a lot of hope and change so he would be voted into office, he is attempting to accomplish those objectives, but the house and senate conservative groupings were highly against him causing them to be delayed. Four years would not be nearly enough to accomplish all of the objectives he promised, but he has setup the foundation and worked to accomplish many.
