Dear XXXXX:
The current situation in the Persian Gulf, brought about by Iraq's unprovoked invasion and subsequent brutal occupation of Kuwait, threatens vital U.S. interests. The situation also threatens the peace. It would, however, greatly enhance the chances for peace if Congress were now to go on record supporting the position adopted by the UN Security Council on twelve separate occasions. Such an action would underline that the United States stands with the international community and on the side of law and decency; it also would help dispel any belief that may exist in the minds of Iraq's leaders that the United States lacks the necessary unity to act decisively in response to Iraq's continued aggression against Kuwait.
Secretary of State Baker is meeting with Iraq's Foreign Minister on January 9. It would have been most constructive if he could have presented the Iraqi government a Resolution passed by both houses of Congress supporting the UN position and in particular Security Council Resolution 678. As you know, I have frequently stated my desire for such a Resolution. Nevertheless, there is still opportunity for Congress to act to strengthen the prospects for peace and safeguard this country's vital interests.
I therefore request that the House of Representatives and the Senate adopt a Resolution stating that Congress supports the use of all necessary means to implement UN Security Council Resolution 678. Such action would send the clearest possible message to Saddam Hussein that he must withdraw without condition or delay from Kuwait. Anything less would only encourage Iraqi intransigence; anything else would risk detracting from the international coalition arrayed against Iraq's aggression.
Mr. Speaker, I am determined to do whatever is necessary to protect America's security. I ask Congress to join with me in this task. I can think of no better way than for Congress to express its support for the President at this critical time. This truly is the last best chance for peace.
Sincerely,
George Bush
