U.S. scientists raise doubts about anti-missile shield

American scientists have expressed doubts to U.S. Congress about the effectiveness of the planned anti-missile defence shield in Europe. They say the system would not be able to provide the U.S. and Europe with protection against Iran and North Korea.A senior advisor at the Centre for Defence Information says the system in its current form is not yet proven in real-life situations.

Russia insists that the possible construction of AMD bases in Poland and the Czech Republic is a threat to its national security.

During the latest negotiations, the U.S. acknowledged Russian concerns and offered to be fully transparent about its plans. Negotiations are set to continue.
