Answer:
First of all, you should be doing your own homework but then I did check here to see if anyone could help me when I had the exact same question to essay.
I would start by describing the Fourteen Points, as this is what Woodrow Wilson believed should be suitable as the peace treaty. Then look at the 'Big Three'; Woodrow Wilson (USA)'s beliefs, Clemenceau (France)'s beliefs and Lloyd George (Britain)'s beliefs on how to deal with Germany.
Then, COMPARE Wilson's Fourteen Points and the Treaty of Versailles (comparison is where you'll get the most marks) and throw in some points about whether Germany were justified to dislike the treaty.
Find some sources e.g. quotes and reference pages to back you up and you can put in your essay as evidence and finish with a strong conclusion!
Hope I helped :)
