Exactly, although I was too colourful and rightly called out for expressing this too forcefully previously. Last I checked, the US was still on DEFCON 4, we'll see if Putin's fancy new "special nuclear deterrence operation" draws a response or raise of DEFCON, depends on what intelligence and . Despite the US being on DEFCON 4 however, we have seen NATO deployments and re-distribution of assets around the globe. We really don't know, thank goodness, what's happening beneath the seas or what's been transferred from SAC bases in the US to places like Bergamo or Diego Garcia, but we can expect we're moving chess pieces all around the board, and will respond appropriately to the "special nuclear deterrence operation".
What this could mean:
1) Putin is aligning forces for a pre-emptive first-strike capability. This is highly unlikely, although he was quoted the other day as saying something about "superior new technology" or something like that. Most likely, I suspect this is a veiled threat that they have developed hypersonic nukes. However, many suspect the US and other NATO allies have also advanced in hypersonic technologies as well. Again, though what would his targets be? Striking the mainland US, UK or France would be unthinkable because the response would be total and overwhelming. NATO bases in Estonia, Romania, Poland or the Baltics? Again, the response would and could be overwhelming. Kaliningrad, basically a heavily militarized district, which lies outside mainland Russia, would probably be the immediate target of a NATO response. Deploying tactical nukes against NATO naval or submarines? Again, this would and could escalate quickly...
2) Deploy against targets in Ukraine? Again this makes no sense, what sense would make to ruin the prize he's seeking to claim? Occupying a country with potions of it a radioactive wasteland is costly, and would defeat the whole purpose.
3) My suspicions, this is pre-text and warning in order to justify conventional strikes against NATO and Western assets, if and when he deems it necessary. The longer the Ukrainians hold out, the more difficult this becomes. For example, we heard about arms shipments from Germany to Ukraine. What if he decides to breach Polish airspace and knock those cargo planes out the air, killing German military personnel? Or hit the NATO bases they arrive at in Poland? The West could also decide to establish no-fly zones to allow humanitarian aid into Ukraine, he could defy those zones and knock out humanitarian airlifts or humanitarian convoys, claiming they were arms shipments or directly confront NATO planes enforcing those no-fly zones. Let's also remember the playbook here, Russia supplied the "separatists" with anti aircraft systems and they shot down a civilian airliner during the 2014 conflict. That lack of a clear "command and control structure" also allows Putin and Russia plausible deniability, if something like that happened. This is what worries me the most, I suspect he's not talking "first-strike" capabilities or deployment against Ukrainian targets, but setting the stage for deterrence as a pre-text for justifying conventional actions against NATO targets, and a warning against no-fly zones or enforcing humanitarian or military aid.
