Not So Fast
Russia should remain a G-8 member for now. It's better to keep the lines open to a power which, like it or not, is a permanent member of the United Nations Security Council, has a significant nuclear arsenal and can't be avoided. In addition, Germany would not agree to a punitive measure like revoking Russia's G-8 membership, which would risk Germany's large investments, trade and energy stake in Russia.
Even though Russia has violated the Budapest Memorandums with the United States and the United Kingdom to respect Ukrainian territorial integrity, and this is a serious matter, the U.S. should try to focus on diplomacy and Western solidarity. Europe, and Germany in particular, is caught in the middle of this crisis and has stronger economic and energy ties with Russia than does the U.S.
