The ''Warsaw front'' is quiet--deceptively quiet--these sunny spring days.
It is almost as though the turbulence of May 3 and May 13 never happened.
On May 13 there was a mixed response to the call for a 15-minute standstill in the factories to mark the close of five months of martial law. It was obviously less than Solidarity's underground hoped for, but more than most official accounts conceded.
Production was not significantly affected. Street traffic was not brought to a standstill. But many people found an unobtrusive way to demonstrate sympathy without violating the military regulations.
The more substantial six-month anniversary is only a few weeks away. Both government officials and the Roman Catholic Church--concerned that May 13 could have sparked more serious incidents--will be still more anxious June 13.
Can something be accomplished before June 13 to relieve the present stalemate in which government and society are ''getting nowhere'' toward the much-talked-about national accord or a solution of the causes of tension between them?
Still paramount is the question of the trade unions. That is even more important than the faltering economic reform or the state of the economy. Poles seem even more resigned to the latter.
The Solidarity underground speaks in several voices. But Lech Walesa, the only person who might be heard with authority throughout the country, is still silenced.
The authorities may be contemplating a change on that. Amid conditions of great secrecy, a senior adviser from the Geneva headquarters of the International Labor Organization visited Walesa at his detention villa just outside Warsaw May 14.
But before the adviser was ferried by helicopter to meet Mr. Walesa, he conferred with senior government officials.
No details of the meeting have been disclosed or leaked here.
Vice-Premier Mieczyslaw Rakowski has just reported on his talks in Vienna last week with Austria's Bruno Kreisky. The Austrial chancellor has suggested Western trade unions might use their good offices to bring Polish authorities and Solidarity realists and moderates together to talk about the future of the union.
That seems a long shot, but Kreisky's consistently moderate attitude on Poland, especially toward the decision to impose martial law, is appreciated here.
Bringing Walesa openly into the picture before June 13 would probably do more to convince Poles of the government's good intentions than its (short-lived) May 2 lifting of the curfew. That caused no special rejoicing because people considered it overdue.
There is little sign of the military presence brought back at the start of May. More police are on the streets, but the troops are gone. The patrols blocking off important midtown intersections have been removed. And television newscasters have doffed ill-fitting uniforms and gone back into civvies.
But there are reminders of martial law. In recent days two high-level Soviet emissaries have been in Warsaw:
Marshal Viktor Kulikov, commander in chief of Warsaw Pact forces, has been here to discuss ''military training and combat readiness'' with Gen. Wojciech Jaruzelski, Poland's military and Communist Party chief.
Konstantin Rusakov, the Kremlin's man in charge of interparty relations within the bloc, has been talking with General Jaru-zelski about ''Polish-Soviet cooperation.'' This cooperation, the official report stressed, ''is essential in consolidating the position of socialism in Poland.''
Poles know what that means, but they pay little heed to the frequent Soviet comings and goings.
Nevertheless the visits serve as constant reminders of the Kremlin's continued interest in how the Polish party is doing in its efforts to regain control of the situation.
