Talk of sanctions and restrictions on Russian goods are likely just that, talk.
Russia is a leading exporter of oil, and one of the US's largest partners for it (given that Iran isn't gonna' be a source anytime soon likely we need 'em). Neither party wants to see higher gas prices at the pump...so no one is likely to do anything
except rattle sabres a bit - much like China does with Taiwan from time to time (as Taiwan has substantial investment in China..particularly in the Fuzhou area and Fijian province).
Buy your Sovvies, EH's and re-issue Tungsol's in the normal qty's you'd buy them in I'd think
