It's the present subjunctive, and 'subjunctive' in English is 'Konjunktiv' in German, although it isn't used in the same ways in both languages.
There should have been many old discussions on this, including a recent query about 'recommend that,' but either I'm blind or there seems to be another black hole in the archives. Yet again.
The present subjunctive is the same in form as the infinitive without "to". This is also the same form as the present indicative, except in the third person singular and in forms of the verb "to be".
The present subjunctive is used: ...
(4) after "that" clauses to introduce a situation that the [speaker] wants to bring about. Used to introduce a formal motion ("I move that Mr Smith be appointed chairman"); after verbs like "demand", "insist", "propose", "prefer", "recommend", "resolve", "suggest"; and after phrases like "it is advisable / desirable / essential / fitting / imperative / important / necessary / urgent / vital that". http://www.alt-usage-english.org/excerpts/fxs...
The present subjunctive ... occurs in 'that' clauses used to state commands or to express intentions or necessity:
· We insist that he do the job properly.
· The committee proposes that she be appointed treasurer immediately.
· It is essential that we be informed of your plans.http://www.bartleby.com/64/C001/061.html
the subjunctive mood ... is also found in clauses following a verb that expresses a doubt, a wish, regret, request, demand, or proposal. These are verbs typically followed by clauses that take the subjunctive:
ask, demand, determine, insist, move, order, pray, prefer, recommend, regret, request, require, suggest, and wish.
