In my country we've had doubts about it for decades but in order not to offend America it was considered politically prudent to buy quite literally any crap the US makes at whatever cost. It's not like we're ever going to war anyway.
It was the same in Romania when joining NATO. They bought a bunch of retired F-16s at inflated prices which pissed off the Romanian taxpayers and the Frech and Swedish governments, since for that kind of money, the Romanian air force could have bought more modern and brand new Dassault or SAAB fighters while also supporting the local EU economy, but instead, they spent the money to buy themselves tickets at the US-ally table (possible corruption and bribes involved as well, but that's pretty much the norm in all defense related purchases)
