Speaking Saturday at the 45th Munich Security Conference, Polish Prime Minister Donald Tusk said the anti-ballistic missile system would be a preventative measure and would play an important role in Europe's security, despite Russia's vehement to its deployment, RIA Novosti reported.
"We are willing to participate in difficult projects because we believe this will underscore our ability to defend ourselves, but also the preventative capabilities of the transatlantic community," Tusk told conference attendees.
He said the anti-missile shield's ultimate deployment rests with the United States. Russia hopes the United States will reconsider the plans under the administration of President Barack Obama.
Tusk also said he supported former Eastern European countries that wish to become part of NATO, even as Russia's relations with the military alliance have deteriorated because of Ukraine's and Georgia's desires to join.
