Did Ukraine change the lessons of the Falklands War?

How has the Ukraine war confirmed, dispelled, or updated the lessons of the Falklands War?

It has mostly confirmed enduring lessons about geography, information, layered defense, logistics, force structure, and political miscalculation rather than creating wholly new rules of war.

The Falklands War provides the historical baseline and the war in Ukraine the modern test. Across littoral danger, amphibious operations, air defense, information, readiness, and sustainment, new technologies alter methods more than underlying strategic problems. The largest difference is geographic and political: Britain could complete a discrete expeditionary objective, while Russia and Ukraine remain locked in an attritional continental war without an equally clear endpoint. Forces, trained people, and support systems must exist before a crisis because capability cannot be improvised after deterrence fails.
