Where do I enter foreign interest income that wasn’t taxable in that country?

I am reporting my foreign earned interest income on a 1099-INT, however I was slightly confused as the explanation for box 1 (Interest income) says “Interest income is the taxable amount of interest paid to you during 2017”. However the interest I earned in my foreign savings account was not taxable in that country. So do I still enter the amount in box 1? If I do, is it because under US law, interest is counted as taxable income?
