Russia closes German cultural centers

The OP is right about the hostage aspect. These centers are low-hanging fruit for the state to use as leverage because they rely entirely on local permits to operate.

The OP misses the mechanism of diplomatic reciprocity. Russia frequently uses cultural assets as bargaining chips to negotiate the status of their own diplomatic missions or frozen sovereign assets.

will the staff be given time to evacuate or are they facing immediate visa cancellations?

We saw a similar pattern after 2014, yet many of those educational links eventually migrated to digital platforms. This shift often preserves the actual exchange even when the physical buildings are closed.

I disagree that the drone plot is merely a pretext. The specific timing and nature of Berlin's accusations gave the Kremlin the precise diplomatic cover needed to justify the move to their domestic audience.
