Russia already tested playbook by doing drafts on the street in limited regions . There’s plenty of videos just Google that . Seems like their strategy will not be all nation mobilized but rather hey , we do in one region , wait , switch to another , repeat .
NATO is half dead , and that’s the main goal of Russia , north Korea , China etc . If they attack the most weak enemy eg baltic counties and claim like hitler did : we achieved what we wanted we just want piece and we are ready to strike piece also with Ukraine , it will :
Prevent any reaction from the nato , since not that many countries within nato will be willing to defend Latvia or Estonia , especially if offense will be complete and successful. Who will defend Latvia ? Germany ? Doubt , Poland ? They do not have a modern army , they still buying tanks and submarines in the age of drones . And Russia do have lots of drones . More than entire nato by a lot of, not to tell if you deduct USA and Turkey , two biggest military NATO powers that will not be eager to defend Baltic regions . Imagine also that Iran will decide to use the moment and coordinate their offensive.
As a result , this few days war can effectively formalize end of NATO and the western world as it is .
