Nobody is expecting the Russians to invade. I think the concern is that they could easily cause widespread unrest here by pitting special interest groups against each other.
Our adversaries and strategic competitors probably already
are looking to the 2020 US elections as an opportunity to
advance their interests. More broadly, US adversaries and
strategic competitors almost certainly will use online
influence operations to try to weaken democratic
institutions, undermine US alliances and partnerships, and
shape policy outcomes in the United States and elsewhere.
