RU Sanctions a Game
Biden Administration to Impose Tough Sanctions on Russia

These pallid sanctions indicate the administration is not wholly confident in the validity of accusations such that strong measures can be taken.
Possibly strong measures are the ones not revealed, at least not yet, depending on how they go and what RU's response is. Pretty common to do that testing before blowing the whistle on covert actions.
Also no need to tell RU exactly what's coming, instead dribble hints without overly alarmist chest-thumping to avoid trip-wires set to ring bells of genuine threats.
In combat rabbits are sent to the front to draw fire and expose defenses, a method so shopworn hardly an experience fighter will fall for it, just blow away the rabbits and wait for main force to walk into an ambush.
Biden, may god protect his honesty, is no rule-breaking fighter (nor was Obama), and has not yet appointed mean, take no prisoners, suffer no fools, SOBs to his diplomatic and national security teams, that is he is not a Putin deeply experienced and dispositioned to engage in genocidal carnage at domestically and internationally, to extend his time in office indefinitely.
Most likely Putin (and to a lessor extent, Xi) will merely endure the Biden diplomatic sanctions pinpricks, brush them off his shoulders, take a horse ride, hang at his palaces, cheer his TLAs, slaughter a gaggle of Ukrainians, off Valany, keep pushing the disinfo and cyber onslaughts against pussy-footing EU and US enfeebled wonkers at lollygagging senior spies at assisted living-ins.
