Responsibility to Protect (R2P)

A maximum 4,000 word essay (this includes sources) is needed based around this topic:
The purpose of this essay is to assess the merits and limits to R2P based on the thesis I am trying to go with below.

The Responsibility to Protect (R2P): Is R2P a weapon used by the West (meaning America and its allies) to enforce western imperialism or is it a doctrine of longevity meant to service human security? Use the 2011 War in Libya as a case study

Here are some of the things I am looking to be addressed:

The overall idea of R2P – including how it was created and introduced
Then a critical analysis of R2P:
Is there selective application of the doctrine?
What’s the idea of R2P being utilized by the West (NATO)
Is it problematic that R2P should be used universally?
Include a critique of how, when, and why it is utilized and why that matters
Talk about the lack of consensus in utilizing R2P due to issues around state sovereignty
Talk about how the application of the doctrine is limited and uneven
Focus on the War in Libya in 2011 and tie it into R2P: how NATO use R2P for the first time to justify intervention into Libya
Talk about how R2P seems better on paper then it practice
Talk about he future of R2P, and how it can be seen more than just a ploy for western imperialism but as a great doctrine for human security and protection.
