BONN, JAN. 23 -- German Chancellor Helmut Kohl, responding to widespread criticism of his country's reticent role in the Persian Gulf, today announced immediate financial and moral support for Israel and scolded anti-American demonstrators who have filled the streets of German cities.

Kohl denounced Iraq's missile attacks on Israel as a "provocation" and said Germany will give Jerusalem $170 million in emergency humanitarian aid because "we Germans have a special responsibility {to protect} Israel's right to exist."

Kohl also said he will soon reveal details of a large increase in German aid to the U.S. war effort. The Bush administration has asked Germany to increase its contribution far beyond the $2.2 billion Kohl pledged when Secretary of State James A. Baker III visited Bonn in September.

Kohl refused to say how much more Germany will give, but said it would be comparable to the several billion dollars that Japan is considering adding to its support. Official sources said the objective was $6 billion. Kohl, who last month handily won reelection while promising that taxes would not increase to pay for German reunification, conceded for the first time that he may have to raise taxes "for some time" to fund Germany's obligations in the gulf conflict.

The chancellor said he will send Foreign Minister Hans-Dietrich Genscher and leaders of all major German political parties to Jerusalem Thursday as a "sign of solidarity."

The Israeli Foreign Ministry welcomed Kohl's gesture as "very positive." A spokesman for Foreign Minister David Levy said Genscher will be "the first to come to Israel" after Tuesday's raid, which killed three people and injured dozens. "With this act, Germany strengthens its moral duty to the Jewish people," the spokesman said.

The chancellor delivered his strongest endorsement yet of the decision to go to war and blasted German antiwar demonstrations, aimed primarily at the United States.

"I can well understand if people take to the street out of their desire for peace," Kohl said. "But I do not understand at all when such actions turn against the United States, which is defending international law in the gulf."

"Those who demonstrate must be asked where they were on Aug. 2, the day Kuwait was taken over," Kohl said. "I am dismayed by the moral indifference, the crass twisting of facts and the definite fomenting of emotions at some demonstrations."

The chancellor's advisers said Kohl hopes the combination of sharply increased aid to Washington and strong rhetorical support for the war will ease the diplomatic damage caused by Germany's divisive debates over whether the U.S.-led attack was justified and whether Germany should help defend its NATO ally Turkey if it is attacked by Iraq.

Asked why he had waited six days before making any major statement on the war, Kohl said he was waiting for the return of his finance minister from the meeting of industrialized nations in New York and for the first meeting of his new cabinet, which took place today.

The Kohl government maintains it cannot send troops because its constitution restricts the German military to NATO territory. Many legal scholars disagree, pointing to an article of the constitution that specifically permits Germany to join international security alliances.

Kohl avoided a clear statement of German policy toward an attack on Turkey, saying only that Parliament would have to discuss the issue. A leader of the opposition Social Democrats called for Germany to withdraw its 18 fighter jets now serving in a NATO defensive force in Turkey, and the chairman of Kohl's coalition partner, the Free Democrats, has said Germany should not defend Turkey if it is attacked by Iraqi missiles.

The chancellor became angry when he lectured demonstrators, who have molded the foreign image of Germans' response to the war. Kohl said it is "a real perversion" when some protesters "display their alleged love of peace with violence." Although most of the daily protests by hundreds of thousands of Germans have been peaceful, there have also been attacks on and blockades of U.S. military installations and of German companies accused of supplying Iraq's chemical weapons and nuclear industries.

Demonstrations continue, with the largest protest yet -- organized by the Social Democrats and numerous unions and peace groups -- expected Saturday in Bonn.

"The people in the street feel moral and are moral," said Wilhelm Knabe, a founder of the pacifist Greens party, which has called on U.S. and German soldiers to desert rather than fight in the war. "The American entrance into the war was not responsible. America should have found a way for Saddam Hussein to save face."

A public opinion poll this week found that 81 percent of Germans questioned voiced support for the war, but 75 percent opposed German participation in the fighting.

Kohl's statement came after the German political and business establishment this week began a drive to counter the impression among Germany's allies that the country's pacifist culture was weakening the anti-Iraq coalition.
