The good ol' Harrol Coyle saga Team Yankee - and maybe that was not even his best one. I have read such stuff more back in those days.
The book I now ask for gets criticism for its demonising of Russia (talking of German comments), but praise for the realism in which the scenario lets the Russians take the Baltic: realistically, and matching schemes of deception we have seen in the Ukraine; cyberwarfare and little green man doing destabilisation long before the military show starst to ignite with loud sounds and bright lights. Greetings from the Ukraine.
The political development seems to be be underdone, but maybe is not the focus of the author'S interest. He seems to have focussed on how such a war would be waged by Russia, and why NATO would get overrolled: doing too litte, too late, and with insufficient forces.
In the Baltic states, immediately after Trumps election they started to disucss what this could mean for the military situation with Russia and these states' military safety (or lack of). In (traditionally Russophile) Germany, at the same time the politicians were stunned, and the media focussed on warnings over gay and lesbian rights, as one commentator bitingly remarked, and he has a point there.
Living in the dnager zone seems to sharpen your senses for priorities.
Sometimes I find it hard not to wish for the West falling.
Well, I take from reading about the book that if the Russians would go for the Baltic, this book describes with great competence how the Russians probably would do it and in what way they would go in - and once they are in, NATO is not likely to get them out again that quickly .
