I need your opinion on the "ranking" of how "in-demand" these courses are: Arabic, Mandarin, Japanese, or Russian.
I'm taking at least one language course each semester for the rest of my college undergrad. I'm currently interning in DC and there really is a mix of everything. I'm continuing my work in the government after I graduate and would like to get involved in military affairs. Arabic seems like the obvious answer but one could make an argument that it could apply to any of these (except Japanese, I guess. They're peaceful with the US).
