A modern-day equivalent might be a right-wing U.S. militia or band of English football hooligans making their way to Moscow, kidnapping and killing Vladimir Putin, seizing Russia’s oil and gas reserves and then declaring the territory a colony, which their descendants go on to dominate for centuries.
This analogy does not feel similar. A modern example might be like 3,000 Navy Seals (infantrymen only) invading South America and subjagating the entire region and using biological warfare to reduce its population size. Political affiliations (right, left, democratic, authoritarian) do not matter so much in this context. The conquest itself was about men overcoming immense odds out of necessity - they would have died if they did not commit themselves fully.
