Col. Muammar el-Qaddafi has written to members of Congress thanking them for criticizing President Obama last week over his involvement in the NATO-led military campaign in Libya.

“I want to express my sincere gratitude for your thoughtful discussion of the issues,” Colonel Qaddafi wrote in the letter, a copy of which was supplied to The New York Times by a person seeking to defend the administration’s policy. “We are confident that history will see the wisdom of your country in debating these issues.”

Colonel Qaddafi did not refer specifically to a resolution passed by the House that rebuked the administration for maintaining an American role in the campaign without the consent of Congress. But he expressed hope that the lawmakers would continue to press the administration.

“We are counting on the United States Congress to its continued investigation of military activities of NATO and its allies to confirm what we believe is a clear violation of U.N. Security Council Resolution 1973,” Colonel Qaddafi said in the three-page letter, which was not addressed to any particular lawmaker.
