Fast-tracking Ukraine's accession to the EU would send a crystal-clear message to Putin: Ukraine has firmly decided that it wants to be part of the European community, and his aspirations of re-building some Soviet-era structure have failed.
While EU membership may seem like a good bargaining chip against Moscow, drawing Ukraine into the bloc draws the West to the precipice of an all-out global, and perhaps nuclear, conflict.
Irrespective of genuine European support for the Ukrainian plight, joining the EU bloc is an ardous process which requires meeting standards on everything from food to bank regulations to human rights. Just ask Turkey, who applied to join in 1999 and is yet to be accepted. The matter is further complicated by the conflict.
