> Countries like Poland will no longer buy US weapons but increase European defense spending - they fear just like Ukraine that US congress just turns around and will stop delivering parts for F-35s in a conflict
Other pluses: American equipment is expensive. The recent purchase from S. Korea is significantly cheaper and IIRC entails a partnership agreement that requires that at least some of the manufacturing happens domestically in Poland. This allows the S. Korean defense industry to establish a base of operation in Europe. Also, the Polish armed forces have been investing in a diversity of equipment (American, EU, S. Korean, and domestic) for some time, which, of course, means they're not too dependent on a single country.
