President Bush warned the Iraqi people yesterday in a taped television broadcast that they are "on the brink of war" because of miscalculations by President Saddam Hussein that have pitted their country "against the world."

In an eight-minute speech that many administration officials had believed would not be broadcast on Iraqi television, Bush said it was not too late for a peaceful resolution of the crisis triggered by Iraq's invasion of Kuwait last month, but he emphasized a growing determination to force Iraq from Kuwait.

"Perhaps your leaders do not appreciate the strength of the forces united against them," Bush said. "Let me say clearly, there is no way Iraq can win. Ultimately, Iraq must withdraw from Kuwait."

In a reply broadcast immediately afterwards, an Iraqi spokesman charged that Bush's statement was full of lies and insisted that the dispute was one between rich and poor, "between Zionism on the one hand and the deprived, persecuted people on the other."

Bush's speech, taped Wednesday in the Oval Office, was delivered to Baghdad by courier after the Iraqi ambassador here refused to accept it. It ran unedited on Iraqi television around 7 p.m. (11 a.m. EDT).

Eight hours earlier, the United Nations Security Council, "outraged" at Iraq's violations of several diplomatic premises in Kuwait, unanimously condemned the violations and said it intends to take "further concrete measures as soon as possible."

Diplomats at the United Nations told special correspondent Trevor Rowe that one possible step is expanding the trade embargo against Iraq to include air traffic.

Meanwhile, hundreds of Kuwaitis fled into Saudi Arabia during the weekend as Iraq opened the border for the first time in a month. Refugees arrived with chilling accounts of dwindling food supplies and the wholesale destruction of homes in neighborhoods where Iraqi soldiers have been killed by Kuwaiti resistance fighters.

The Iraqis made no announcement of the border opening; the news spread by word of mouth. Some refugees assumed that Iraqi forces wanted to get into their homes. Others believed it was part of a plan by Saddam to repopulate Kuwait with Iraqis. The Associated Press said a fleeing journalist told of a friend who got an anonymous phone call saying: "Why do you always talk badly about Saddam Hussein? The border's open, why don't you leave?"

In his remarks, Bush emphasized to the Iraqi audience that "Kuwait was the victim; Iraq, the aggressor" in the Aug. 2 invasion and pointed out that 27 nations have sent forces to the Persian Gulf region in response to requests from Saudi Arabia and Kuwait rulers in exile.

"For the first time in history, 13 states of the Arab League, representing 80 percent of the Arab nation, have condemned a brother Arab state," Bush said. "Today, opposed by world opinion, Iraq stands isolated and alone."

Reminding Iraqis of the suffering and hardship of their eight-year war with Iran, Bush said: "Now, once again, Iraq finds itself on the brink of war. Once again, the same Iraqi leadership has miscalculated."

Bush also accused Saddam of misleading Iraqis, by telling them Iraqi forces had been "invited into Kuwait" and depicting the crisis as a struggle between Iraq and the United States.

"In fact," Bush said, "it is Iraq against the world. When {Soviet} President {Mikhail} Gorbachev and I met in Helsinki, we agreed that no international order is possible if larger states can devour their neighbors. Never before has world opinion been so solidly united against aggression."

"The pain you now experience is a direct result of the path your leadership has chosen," the president said.

How much of an audience Bush had was unclear. The Iraqi media gave no advance notice of the broadcast and it appeared at 7 p.m. on Channel One, which usually broadcasts local news at that time. The competition on Channel Two was an Egyptian adventure cartoon.

At a working-class cafe in Baghdad's Bab al-Sharji district, Reuter reported, patrons sat in a semicircle around a TV set intently following an Egyptian love story that ended at 7 p.m. Some then watched the cartoon that followed. Others drifted away. In a nearby teahouse, men played dominoes and chatted while the Iraqi spokesman, Mikdad Morad, accused Bush of wanting to become "dicatator of the whole world," in the broadcast that followed Bush's speech.

Morad, who usually reads statements in Saddam's name, spoke on his own this time. U.S. officials said Saddam had undoubtedly endorsed every word. The White House described the response as "a half-hour diatribe" and said in a statement that Bush's message "must have been effective in view of the extraordinary effort taken to discredit him."

Describing Saddam as the "son" of the Iraqi people and "not a leader created by the CIA," the Iraqi statement denounced Kuwait's rulers as "corrupt" individuals who were "stealing Iraqi oil" and "were always in favor of the imperialists." Morad also assailed Bush for suggesting that most of the Arab world is opposed to Iraq rather than the United States. He said Bush was ignoring "what's happening on the streets of the Islamic and Arab world."

In Baghdad, as if on cue, demonstrators marched through streets shortly after the broadcast shouting "Death to Bush, death to America," and denouncing Egyptian President Hosni Mubarak and Saudi King Fahd as "traitors of the Arab world" for backing the multinational troop buildup in the gulf region.

According to Reuter, witnesses in one Baghdad suburb said demonstrators arrived in government buses, even before the Bush broadcast, complete with anti-Bush banners and posters.

At the United Nations, talk of a tighter embargo against Iraq was complemented by suggestions of secondary sanctions against countries or companies that violate the embargo. There are persistent rumors that goods have been shipped to Iraq either from or through Jordan, Yemen, Iran, Tunisia, Libya and Lebanon.

"The {Security} Council committed itself to take further action very firmly today and we will begin active consultations," U.S. Ambassador Thomas R. Pickering told reporters after the vote. It was the seventh resolution against Iraq since the invasion.

The Security Council resolution, adopted at 3 a.m. by 15 to 0, was a direct response to raids by Iraqi troops against the diplomatic missions in Kuwait of France, Canada, Belgium and the Netherlands. Four French nationals were seized -- including the military attache, who was later released.

Sabah Talat Kadrat, an Iraqi representative, told the Security Council that the news regarding the French diplomat was false and that France was responsible for the escalation in tensions.

Italy responded yesterday by expelling all officials at the Iraqi military attache's office in Rome and restricting the movement of other Iraqi diplomats. France already had expelled some Iraqi diplomats and increased its military forces in the Persian Gulf.

A senior official here said the White House hoped the Bush message would "encourage internal opposition" to Saddam and "public questioning" of his policies in the gulf. The White House had threatened that if the tape did not air, at least in edited form, it would be released worldwide on Wednesday.

The Iraqis had never offered to put a Bush speech on television. They had proposed to send a film crew here to "interview" Bush. The White House immediately framed the issue in its own terms by describing the proposal as an offer to broadcast a Bush message in Iraq.

Meanwhile White House national security adviser Brent Scowcroft said yesterday the United States has "no concrete evidence" that Iran is violating the embargo against Iraq, despite a diplomatic rapprochement between the former warring nations. Iran has said it would observe the sanctions "and we see no reason not to expect them to," Scowcroft said on CBS's "Face the Nation."

A senior administration official said in an interview that the administration was "somewhat uneasy" about Iran's posture but said third-party discussions with Iran convinced the United States that Iran does not intend to break the embargo at this time because of its desire to start rebuilding its economy with the help of Western countries outside the United States, especially West Germany and Japan.

However, this official said, Iran "at this time" cannot side publicly with the United States on anything.
