We, the undersigned, are outraged at the open aggression of the Russian Federation and of Vladimir Putin’s breach of international law and existing treaties guarantying Ukraine’s sovereignty and territorial integrity.

We demand the immediate suspension all civilian air traffic within the United States of Aeroflot Airlines and all other air carriers of the Russian Federation unless the Russian Federation withdraws all claims of legitimacy of the illegal and destabilizing referendum held in Crimea on March 16, 2014 and until the Russian Federation withdraws all its regular and “unidentified” armed forces from the territory of Ukraine in conformity with international law and existing treaties.
