The Soviet Union and West Germany are condemned to dialogue. They need each other politically and economically. And however irreconcilable their positions on Euromissiles, they are not going to break off that dialogue.
This seems to be the message - according to both Western and Soviet analysts - of the first visit to the Soviet Union by a conservative West German chancellor in more than a quarter century.
''Precisely at a moment when there is an especially critical situation between East and West, such dialogue is necessary,'' West German Chancellor Helmut Kohl told a press conference during his July 4-7 Soviet visit. Dr. Kohl also indicated that his talks dealt very much with long-term Soviet-West German relations rather than just dwelling on the current feud over Euromissiles.
In similar vein, on the Soviet side a senior official told The Christian Science Monitor: ''Relations between the Soviet Union and West Germany are important for both sides. Therefore a dialogue is always useful. And in a time when there are great tensions I would say it is all the more useful.''
Certainly the next year does promise to be one of ''great tensions.'' The public Soviet emphasis on this bilateral get- acquainted summit has been on General Secretary Yuri Andropov's solemn warning that the stationing of new NATO missiles in West Germany would create a radical new situation on the European continent.
And in more direct language Soviet Premier Nikolai Tikhonov stated in a toast that new deployments ''would mean for the first time in postwar history a military threat again stems from the German soil to the Soviet people.'' He continued: ''We and our allies will respond by taking without delay additional measures to strengthen our security and develop a counterbalance to NATO's new military potential.''
