In no way it is credible. Where are aircrafts and helicopters? How about Poland delivering howitzers (2S1 and Krabs) and SAMs?

That is exactly why we (EU) can no longer rely on any (especially sensitive like on this example) technology originating from US and must develop our own substitutes as quickly as possible. That, on the other hand, may boost industry in EU countries that e.g. Poland may benefit from.

and any weapons purchases from outside EU (especially US) needs to be reconsidered. We cannot afford to be blackmailed in the future by defense technology providers.
