The Organization of American States has passed a resolution condemning terrorism and has called for the study of terrorism and has called for the study of terrorist attacks and their accompanying extrortion.

The resolution to study terrorism, proposed by the Dominican Republic, passed virtually unopposed and unchanged late last night by the OAS seventh General Assembly here.

The speed with which the resolution passed was seen as an encouraging sign for the chances of a U.S. proposal aimed at strengthening human-rights considerations in the Americas.

The U.S. resolution, which is also sponsored by Venezuela, costa Rica, and the Dominican Republic, will face its first real test today when it is discussed in a 15-country committee formed to reach a consesus on the remaining resolutions on human rights.

The main problem facing the United States is to head off any attempt to suggest that violating human rights is acceptable when done as part of a struggle against terrorism.

OAS sources said that Argentina is expected to attempt to have some reference to this included in the American proposal or, falling that, to try to water down the resolution.

The fact that a resolution has been passed dealing solely with terrorism is seen here as a precedent that indicates that the assembly is ready to consider separately the two related problems of terror and human rights.

Ambassador Gale McGee, the U.S. representative to the OAS, said that passage of the resolution probably meant that the OAS would "make a good and firm resolution on human rights."
