An interesting if opinionated take:

Past couple of years have seen a dramatic escalation in Russian infiltration and sabotage shenanigans in the Baltic and in nearby states (eg. in Finland and Sweden), targeting strategic locations, testing various aspects of their defenses and compromising control systems and other key components of important infrastructure and services such as power, communications, financial services, healthcare, etc. Espionage and tampering with the democratic process using disinformation and the like, that's business as usual. But these other more overtly military activities--and esp. the escalation--feel like the build-up to a more concrete operation.
So what do you guys think? Will Russia make a serious move on one of the Baltic states in the next couple of years? Will it do anything to seriously test Article V? Will NATO pass the test? Is there anything that can be done to forestall a war in--or a takeover of--the Baltic states? I think we've moved beyond the point where typical political and military posturing can be reasonably expected to accomplish enough of value.
