Anyone pls explain about Deuteronomy 7?

I haven't found anything in the Old Testament / Torah that says anything about peace and love and brotherhood between God's favorite people and the rest of the human race. It's all about killing and destroying and plundering the gentile nations, not about loving them. In the book of d'varim, for example, it states rather plainly that God has a favorite people, and do you think you can guess who they are?
