Globalisation: proliferation of american hegemony

I would like to have an essay of about 2000 (two thousand) words, with introduction (about 250 words), body (about 1500 words) and conclusion (250 words). It should also include an argument at the beginning and the whole analysis should be built up according to that argument.
the topic is discussion whether globalisation is a smooth global integration, or an Americanization, e.i. expnasion of American power. this should include a particular case study providing me (an author of essay) with the evidence against which an argument/evaluation of this issue can be constructed.
