There will be no WTO involvement, national security is specifically exempted from WTO review. Article XXI: the security exception in states that a country can not be stopped from taking any action it considers necessary to protect its essential security interests; actions "relating to the traffic in arms, ammunition and implements of war and such traffic in other goods and materials as is carried on directly for the purpose of supplying a military establishment (or) taken in time of war or other emergency in international relations." The reality of the situation is NPO Energomash has ULA by the you know what while at the same the US Defense Department has NPO Energomash in a huge bind. If the US DoD ever decides to throw ULA under the bus Energomash is in big trouble.
