What kind of programs/solutions can only be written with OOP or are too hard to achieve without it? [closed]

Question

Paraphrasing a recent question: https://softwareengineering.stackexchange.com/questions/52608/what-is-object-oriented-programming-ill-suited-for

I would like to ask the opposite question:

What kind of programs cannot be written unless you use OOP?
What kind of programs are not recommended to be written using non-OOP techniques?
What kind of programs need OOP in order to even be written? What kind of programs would be too hard to write without OOP ?

The answer to this question can help sell the idea of OOP to project leaders that have no special interest in code quality. At least they could buy the idea if one shows them the kind of things that are not even possible unless you use OOP.
