First he says all limitations are off the table

Tbf, he did not.

One of the many failings of Merz is, that he is a terrible communicator.
What he said was: “All range restrictions have been lifted”, which was understood by most to be the announcement of a new policy change.
But actually he was just referring to something that had already happened half a year earlier under Scholz.

His defenders will point out, that what he said was factually true and that he did not announce anything new. But once again, Merz seems incapable of considering the context under which such questions are asked and how his words would be interpreted.
