During his visit to Berlin, Polish President Duda also proved that he is not a willless executor of PiS chairman Kaczyński's anti-German policy.
Despite Putin's war of aggression on Poland's doorstep, the latter did not refrain from straining relations with EU and NATO partner Germany with his demands for reparations.
Warsaw's erratic course in the matter of Patriot missiles may also have had something to do with the fact that a German offer to help defend Poland does not fit into the gloomy picture that Kaczyński paints of the Germans at every opportunity.
But the forces in the Warsaw government that had welcomed the offer as soon as it became known have obviously prevailed.
Duda also thanked Berlin for this "very important gesture by an ally and neighbor".
However, Warsaw is sticking to the condition that the German soldiers have to be placed under Polish command.
But that should be a solvable problem.
Is Kaczyński happy too?
It is not yet known how happy Kaczyński is about the agreement and the conciliatory tone between Duda and Steinmeier.
But one person definitely doesn't like the president's pact that they want to remain bridge builders: Putin.
He follows closely whether there are any cracks in the “collective West” that he could enlarge with the means at his disposal.
The Russian attacks on the Ukrainian electricity, water and heat supply facilities are not only intended to wear down the Ukrainians' powers of resistance, but also to trigger a new mass exodus to the West in order to stoke internal political conflicts there.
Germany, Duda is right, should prepare for it.
However, the best thing would be to help the Ukrainians in such a way that they do not have to flee.
The country now urgently needs not only tanks, rockets and grenades, but also generators, transformers and pipelines.
