WARSAW — Washington’s pullout from the missile defense projects in Poland and the Czech Republic has been received there with disappointment. Not so much because of the logic behind the decision, but mostly because of the arrogant way it was sold to the world, trampling previous informal arrangements. The credibility of U.S. foreign policy was dealt a painful blow.

Some of the people who 12 months earlier were making the case for the missile defense installation in Poland and the Czech Republic today are equally vocal in naming the project’s faults.
