The United States must do everything it can short of military intervention to stop carnage in the former Yugoslavia, said U.S. Sen. Nancy Kassebaum, R-Kan.
"I don't think people are ready to send in ground troops," said Kassebaum, a member of the Senate Foreign Relations Committee.
On Monday, Kassebaum spoke to journalism, political science and law students at Kansas University.
In Bosnia-Herzegovina, Serbs have been fighting Muslims and Croats in in a war that has left at least 124,000 people dead or missing.
Kassebaum said more pressure was necessary to persuade Bosnia's Serbs to sign a United Nations peace plan. Croats and Muslims already have accepted the plan.
The U.N. should tighten economic pressure on the Serbs, Kassebaum said. That includes stepped up enforcement of the embargo on shipments to and from Serbia and seizure of Serbian assets in foreign banks, she said.
The senator endorsed enforcement of the U.N.-imposed no-fly zone over Bosnia. NATO warplanes began patrols over Bosnia on Monday.
More humanitiarian aid must get to Muslims and Croats under assault by Serbs, she said.
"Clearly, there's got to be a better way to provide humanitarian care to these people," Kassebaum said.
On another pressing foreign policy matter, Kassebaum said the United States should provide the former Soviet republics with more than $1 billion in aid.
She said the republics, especially Russia, must move forward with a difficult transition to a market-oriented economy.
"It won't really do any good if Russia doesn't have economic reform," Kassebaum said.
Kassebaum said the United States was right to send American troops to Somalia.
"We really needed to be there because it was complete anarchy and there was no government," she said.
Kassebaum said the United States must carefully consider involvement in international conflicts.
"We can't be the world's policeman or the world's nanny for that matter," she said, "but we do have a leadership role."
