In the case of at least one state separatist movement (and at least one white power movement, IIRC), both were revealed to have leaders who traveled back and forth to Russia and/or received funding.
I would also invite you to go back to the origins of the Trump campaign, and see how it evolved. It originally began as an active measure, with the Trump campaign hiring paid actors to promote his campaign announcement. There's a paper trail behind this, and several of his former staffers have come forward recently and admitted it.
You just described US foreign policy in South America and SE Asia.
Somehow people think the United States is too big or too exceptional to be the target of agitprop.
This theory is like a mirror image of what the empire is doing to the world.

Further, the successful use of cyberwarfare by Russia, is considered the leading example of its kind.
And I haven't even mentioned Brexit, or hundreds of other campaigns to weaken western democracies.
It's pretty clear that Russia leads in this regard.
The invasions of Afghanistan and Iraq were worthless failures, and resulted in the loss of trillions of US dollars that could have gone to building American infrastructure, funding universal healthcare and education, and improving the lives of average citizens.
These invasions fundamentally weakened the US at home and abroad. They did not serve the interests of "empire" at all.
We seem to be talking about different things.

> The book emphasizes that Russia must spread anti-Americanism everywhere: "the main 'scapegoat' will be precisely the U.S...Russia should use its special services within the borders of the United States to fuel instability and separatism, for instance, provoke "Afro-American racists". Russia should "introduce geopolitical disorder into internal American activity, encouraging all kinds of separatism and ethnic, social and racial conflicts, actively supporting all dissident movements – extremist, racist, and sectarian groups, thus destabilizing internal political processes in the U.S. It would also make sense simultaneously to support isolationist tendencies in American politics".
Facebook, Twitter, and other platforms became publishing platforms for active measures (propaganda and disinformation) campaigns to promote Russian-style authoritarianism and diminish the influence of western democracy.
Once these platforms were given this evidence (widely published and released online by the platforms themselves), they took some steps to stop it.
Notable examples include populist movements such as the Trump campaign, state secession movements, white separatist movements, and more recently anti-vax movements. There are many more.
Facebook in particular has failed to stop the spread, and the site is widely considered by most outside experts as "captured" by foreign assets. This is especially true when it comes to QAnon and anti-vax content, which appears to be promulgated to harm western institutions.
