Swiss politicians are questioning the reliability of the U.

S. as a partner under Donald Trump's leadership, particularly regarding the F-35 fighter jet deal.

Concerns have arisen over whether the U.

S. will honor the fixed price of six billion francs for the jets, as production costs are expected to rise.

SP's Sarah Wyss has called for the contract to be reconsidered, citing financial and security risks.

Meanwhile, FDP leader Thierry Burkart advocates for prioritizing European manufacturers in future defense purchases.

The debate highlights growing unease about Switzerland's dependence on the U.

S. for its military modernization.
