preventing an aggressive foreign nation from directly influencing your population

You didn't mean Israel? US is completely ruled by Israel first agenda. DNC lost on purpose because Trump had most of the Zionist funding, and all oligarchy/Christofascist/media just allies with Israel first agenda to get their sliver of power. That US public aid flows circularly back into election funding is direct determination of election results. Every god damn thing is absolutely directly the result of Zionist first rule over America.
