Making a god out of blood mean to force your beliefs through wars/coercion rather than superiority. If you made a god out of superiority it implies that your beliefs are those that are sound and worthy of followers rather than just enforcing your beliefs on others. This is likely a lash-out at nations that (most obviously the US but other colonial powers too) who impose their system of beliefs/philosophies/laws on others simply through intimidation tactics rather than the inherent superiority of these systems.
