Poland will not get spare parts for its F-35 in a conflict under Trump, or more likely be blackmailed for higher prices or other concessions. Or the software will stop working and they need to pay to make it work again. Trump would love that.

The only way for Poland to be safe is having military production in its own country. Because it's easier if everyone has the same weapons, I it should join Airbus and KMW+NEXTER and get production facilities on it's own land.

As seen with AstraZeneca you need physical control to be safe.
