PARIS, FEB. 15 -- The European allies and Japan joined the Bush administration today in rejecting the conditions that Iraq attached to its proposal to withdraw from Kuwait.

After a flutter of jubilation when it appeared that Iraq might commence an unconditional withdrawal, hopes were dashed by Baghdad's conditions that the allies withdraw their forces from the region and rebuild Iraq; that Israel withdraw from occupied territories; that the United Nations repeal its resolutions condemning the invasion, imposing economic sanctions and authorizing force; and that Kuwait's ruling family not be restored to power.

German Chancellor Helmut Kohl, speaking at a joint press conference here with French President Francois Mitterrand, said he was disappointed that the Iraqi offer "does not fulfill" the requirements laid down by the U.N. Security Council because "it creates a link with a whole series of conditions before a withdrawal."

As a result, Kohl said, he did not believe the Iraqi offer represented a significant change of position because it clearly fell short of U.N. Resolution 660, which calls for "a complete and unconditional withdrawal from Kuwait."

Mitterrand said the Iraqi statement "seems more a question of diplomacy by propaganda than a real desire for a settlement" based on the U.N. resolutions. The French leader noted that there was "at least something new" in that Iraqi President Saddam Hussein "this time envisions an evacuation from Kuwait." But he stressed that the Iraqi offer cannot be accepted as long as it presents "unattainable conditions."

French officials said Foreign Minister Roland Dumas spoke by telephone with Secretary of State James A. Baker III immediately after the Iraqi announcement to begin coordinating the allied assessment and response. Dumas told Baker he had discussed such an eventuality -- and the need to avoid falling for an Iraqi "trick" -- with Soviet President Mikhail Gorbachev in Moscow on Tuesday, sources said.

British Prime Minister John Major also firmly rejected the Iraqi offer, describing it as "a bogus sham." He said Iraq will have to produce tangible evidence that its troops are leaving Kuwait before the world community takes seriously the notion that Iraq is willing to end its occupation "decisively and irreversibly."

Japan, which has been criticized for not making a greater contribution to the war effort, made it clear that it shared the reaction of the United States and the other allies. Prime Minister Toshiki Kaifu said Japan would study the offer, but noted that the Iraqis "have attached conditions that don't conform with U.N. Resolution 660."

Prime Minister Felipe Gonzalez of Spain, who had called for a halt in allied bombing raids on Iraqi cities after an explosion in a Baghdad building killed scores of Iraqi civilians, said the Iraqi offer could be viewed in an optimistic light only if it respected all U.N. resolutions.

"At this moment, the Iraqi communique should be considered a hypothesis, and coalition leaders should evaluate it with great prudence," Gonzalez said.

None of the European allies called for a halt in the war on the basis of the Iraqi offer, and they insisted that the bombing raids on military targets would continue until Kuwait is finally liberated. Mitterrand said that "as Kuwait is still occupied by the Iraqi army, that army is going to receive some blows."

But German opposition leaders, who repeatedly have called for a cease-fire, once again requested a pause in the war. An interruption in the war was necessary "to give policy a new chance," said former chancellor Willy Brandt, a leader of the opposition Social Democrats.

Among allied governments, Italy offered the most sanguine evaluation of the latest Iraqi announcement, as senior officials expressed the hope that it would be a prelude to a peaceful settlement.

Nino Cristoforo, a top adviser to Prime Minister Giulio Andreotti, said "it seems to me that glimmers of peace are emerging." He said the allies' firm support for the U.N. resolutions "can induce Iraq to change its mind."

But Andreotti said in a written statement that "caution is called for. . . . There is a need for intentions to be immediately translated into concrete actions in line with the resolutions of the United Nations."

Nonetheless, the Italian leader said he was pleased by the recent Soviet diplomatic contacts with Iraq, which "lead one to consider that a political way out of the crisis is possible."

Soviet envoy Yevgeny Primakov said he found some reason for hope during his talks with Saddam in Baghdad a few days ago. Primakov, who was visiting Tokyo today, indicated that the Iraqi proposal could be a positive step. "If {Saddam} had to choose between a settlement and a war to the end, he would choose settlement," Primakov said.

Iraqi Foreign Minister Tariq Aziz is expected to arrive in Moscow on Sunday and will meet with Gorbachev on Monday. Andreotti said the visit by Aziz to Moscow this weekend will offer "the possibility to clarify" Iraq's true intentions.

Italian Foreign Minister Gianni De Michelis called the Iraqi statement "a sign of weakness" after one month of war, and said it could be "an extremely important signal" that bears further scrutiny.

De Michelis and two other foreign ministers from the 12-nation European Community will travel to Moscow this weekend to meet with Soviet Foreign Minister Alexander Bessmertnykh. The European delegation hopes to meet separately with Aziz to learn more about what may lie behind today's announcement in Baghdad.
