As Charles Grant, director of the Centre for European Reform, told me, "Poland has traditionally been a close ally of the US on security matters, but that alliance has become strained in recent years". "Poles were upset by President Obama's abrupt cancellation of the Bush administration's plans for missile defence, which would have stationed interceptors in Poland, and they are still arguing with the Obama administration about whether the Patriot missiles that Poland wants should be based there permanently or not," he added.
