Four Noble Truths contradicting?

I don't even like to post a question like this but I just want to share a misconception that people from other beliefs have regarding Buddhism. Please what this video https://www.youtube.com/watch?v=c0ws36pd-Q0 .

What this person says is that according to the third noble truth sorrow can be eliminated by getting rid of desire. And when desire is eliminated there is no reason to have a fourth noble truth which talks about the 8 fold path. This is just absolute illogical and misleading statements. But I just do not have the proper knowledge to make my Muslim friends understand why this is wrong. Please do share your views. Thank you
