Suitable SAT for International Relations major?

I am currently a High School junior, and i am going to be taking two SAT Subject Tests this year, and i am planning on majoring in International Relations. I am thinking of testing on SAT II World History because that would definitely go with my major. But i don’t know what else to take it on? I don’t prefer US History because i take AP this year, and that class is going very bad so i don’t think i will be prepared for it. However, i have been taking Spanish for the past 4 years, but i couldn’t fit it into my schedule this year so i don’t know about that either. And I plan to do something in the law/business field as a career. So please recommend some subject tests that will look good for my intended major. Thanks!

Foreign language would indeed be relevant (and, depending on the school, could be expected. Tufts or Princeton pretty much expect it.)

Foreign language or US History would be good.
