Yeah, either click on that 'd' or I just hit shift-d to contact that civ. Then click on "I would like to propose a deal". Then at the bottom you will see 'New' and 'Active'. New is what you currently would like to offer, and active is treaties you already have in place. Click on 'Active'. Then if you already have a treaty in place you will see a number beside it to tell you how many turns are remaining. For example (15) Peace Treaty, means there you must wait 15 more turns before cancelling peace. With no number, it means the treaty is still in place, but you can freely cancel it at any time.
If no number is in front of the peace treaty just click on Peace treaty to cancel it and declare war. This is the honarable way of declaring war (if you also don't have any other treaties with them and your units are not inside their territory).
