I would much rather that Polish diplomats use Polish and qualified interpreters rather than trying to use English. I'd make an exception for those with substantial life experience in anglophone countries but it's too dangerous to try diplomacy in a foreign language (it's far too easy to agree to something you didn't intend to or don't fully understand).
The only alternative would be for Poland to self-colonize and make English the number one priority of the entire education system (like a lot of former british colonies do). But that's not a good strategy either.
