to intervene
To actively get involved in a matter, conflict, or development in order to influence it or bring about a solution. Often used in political, diplomatic, or social contexts.

'Intervenieren' (to intervene) is a formal word used mainly in written language or in formal contexts such as politics, diplomacy, and medicine. In normal everyday life, it is rather rare.
Der Moderator musste mehrmals intervenieren, um die hitzige Debatte zu beruhigen.
The moderator had to intervene several times to calm the heated debate.
The appropriate preposition depends on the context. You intervene 'in' a matter (a conflict, a debate) or 'bei' (with/at) a person or event.
Die Zentralbank hat am Devisenmarkt interveniert.
The central bank intervened in the foreign exchange market.
The context makes the meaning clear. If it is about politics, conflicts, or social issues, it means 'sich einmischen' (to get involved/interfere). In connection with doctors, hospitals, or operations, it means 'einen medizinischen Eingriff vornehmen' (to perform a medical intervention).
Die Opposition fordert die Regierung auf, in der Wirtschaftskrise zu intervenieren.

In political or social contexts, the verb is often combined with adverbs such as 'diplomatisch' (diplomatically), 'militärisch' (militarily), or 'verbal' (verbally).
Mehrere Länder drohten, militärisch zu intervenieren.
Several countries threatened to intervene militarily.
to treat / to deal with
'behandeln' and 'intervenieren' can both have to do with taking active action in a difficult situation, especially in medicine. However, 'behandeln' is broader: a doctor treats an illness, or someone treats a person in a particular way. 'intervenieren' more strongly means that you intervene in a development, a conflict, or, in medical contexts, a condition in order to change something. The word often sounds more technical or official. The words are easy to confuse because a medical intervention can be part of treatment. But not every treatment is an intervention.
