The most difficult language to learn

What is the most difficult language to learn?
for a native English speaker... I think it's Chinese :(

For English speakers it would be Korean because of the pronunciation, if you are slightly off in most of the languages, people will understand you but when speaking Korean, your pronunciation cannot be slightly off. Chinese difficulty is overrated.

Korean is not so hard. i want it to be my third language.
Chinese is way harder. at least Korean allows for accents
