Xiden already threatened economic sanctions for invasion (and made some kind of gesture that got Putin smiling https://conservativebrief.com/biden-8-55984/?utm_source=CB&utm_medium=ProTrumpNews) Russians are right now giving each other high fives, breaking out the vodka in celebration and choosing which date to march into Ukraine. Russians already know what sanctions from USA look like after Xiden already approved the oil pipeline with no Russians asking - Russian system is grab what you want. This means they get to have anything else they want next on their wish list since USA will do NOTHING.
