Hanna, I am so glad that these sanctions occur. At last we can say "get lost!" to our "western partners", build our own clearing system, turn to payments in rubles only, becoming more oriented to Asian markets. These steps can cause collapse of the US dollar. Thank God, it happens! Yahoo!

Would you consider it a serious problem if you couldn't use your Visa / Mastercard.
Hanna, if it's really necessary, I'm ready to donate my own $1000 to ruin American economy. As a payment for their "services". So any steps in this direction are excellent, even if they produce some temporary troubles.
