GRAPEVINE, TEX., AUG. 28 -- House Speaker Jim Wright (D-Tex.) met with Nicaraguan contra leaders today and refused to say whether he would go along with their proposal to put U.S. military aid in escrow in case peace negotiations with the Sandinista government fail.

Six members of the civilian directorate governing the Nicaraguan resistance conferred with President Reagan in Los Angeles Thursday and proposed that the aid be held in abeyance to show their commitment to peace.

Wright met with contra directors in a hotel at Dallas-Fort Worth International Airport. After the meeting, he held a news conference with the three -- Alfredo Cesar, Alfonso Robelo and Aristides Sanchez.

"I never did enter into any enterprise in my life anticipating its failure, because if one does that, he sows the seeds of its failure," Wright said.

Reporters asked Wright if he would agree with the contra escrow proposal, but he steered clear of a definite answer and finally said he was not ready to make a commitment on the subject.

Instead, Wright said, he would rather discuss humanitarian aid to the contras.

"There is money in the pipeline already committed, already appropriated," Wright said. "We've been talking about creative ways to use whatever money there is for peaceful processes. Let's call that humanitarian aid.

"I'd rather spend some money sending in a peace corps, sending in a literacy corps, sending a medical corps. Then we won't have to send the Marine Corps," Wright said.

Wright also would not speculate on what tack Congress might take toward the funds and peace talks.

"I'm not ready to spell out exactly what formula Congress might be willing to support. The fundamental concept is we're going to give peace a chance," he said.

Wright said he had some indication that the Soviets would do their share toward a peaceful end to the Nicaraguan conflict by withholding military aid or supplies to the Sandinistas.

He said there were also indications that the Nicaraguans were going to ask the Soviets and the Cubans to honor the peace negotiation terms.
