Polish President Accuses Obama of Betraying Poland

The statement comes after the President cancelled the construction of a missile defense system promised during the Bush presidency.

Reflecting Warsaw's long-standing anger over the 2009 cancellation of a controversial Bush-era anti-ballistic missile system President Bronislaw Komorowski said Poland should build its own missile shield to ensure national defence.

"Our mistake was that by accepting the American offer of a shield we failed to take into account the political risk associated with a change of president," said Mr Komorowski in a magazine interview. "We paid a high political price. We do not want to make the same mistake again. We must have a missile system as an element of our defences."
