Practise is good, but exhaustion is bad. Russia is getting exhausted, which is why their influence collapsed in Syria, Azerbaijan and Armenia, allowing the US to overtake those vacuums.
The US in WW2 staged their 20th century by letting others (China, South East Asia and the British/Soviets) get exhausted first. This was more an accident of geography rather than US grand strategy, but it worked all the same.
Currently conflict is a really good sales pitch for buying more interceptors.
You could expect order books to get so thick that production increases.
I mean looking from the side lines, I could see why many countries might want to have a few interceptors on hand. Just in case, it's certainly a nice way to buy some time.
