Ford, Pepsico, Exxon and Alcoa don’t want heavy sanctions. I suspect they have some pull.
BTW, my guess is that Russia would be very slow to confiscate property from Western companies. Even the appearance that they might do that could cause flight. More likely they would enlist them in a little regime change action at home; that a flood of corporate cash would inundate if some big bang up with Russia was bad for bidness. Bidness has some pull in American politics.
That’s why most of us laugh at the neocon hysteria over this nonsense. It’s very unlikely that even a hardcore neocon devote like Romney or even McCain would really do anything. If they did, they would get their wings clipped real quick by their paymasters.
