Is Indonesian an easy language?

Indonesian is a language that I'm thinking about learning
Is it true that it is one of the easiest languages to learn?
How long would it take to become fluent?

I assume Barack Obama learned Indonesian when he studied there
as a boy. Does he know the languages of Kenya? What other
languages does he know? Did his stepfather taught him arabic.
Anyone know?

I want to know the benefits, countries where the languages are spoken and other interesting stuff

How/Where Can I Learn To Speak Indonesian In 4 Years

Hey my name is Alex and I'm 14 years old. I speak 4 languages: French, English, Spanish, and Hungarian, but I also want to learn to speak Indonesian because one day I want to live and work there. I have a best friend whose Indonesian and maybe I can practice the languiage with her? Or if there are any online websites that help teach you Indonesian in 1-4 years.

Thx for all your support,
Alex
