Last year, NATO officially declared that Russia is its primary adversary, officially restarting the Cold War. Since then, the belligerent alliances war machine has started revamping its strategic posturing towards Moscow, but after decades of numerous wars of aggression against relatively helpless opponents, NATOs conventional fighting capabilities have atrophied significantly. This seems to be affecting all branches of major NATO militaries, including their air forces, particularly those operating the deeply troubled F-35 JSF (Joint Strike Fighter), a pan-Western effort to unify all NATO and NATO-aligned countries into a well-oiled joint fighting force with near flawless coordination and battlefield information sharing. At least that was the original idea.
However, the reality is much different. Publicly, the Pentagon is quite happy with the best fighter jet ever made. Privately, the situation is starkly different. For at least a decade, numerous reports on the F-35s countless flaws have turned out to be not only true, but even overoptimistic, as the actual scale of issues plaguing the program is much worse. This has resulted in repeated delays in deliveries, as well as serious issues with modernization efforts. By the time many of the reported issues are resolved, the US Air Force already has new mission requirements that essentially nullify all the previous work and force the developers back to the drawing board. In short, the F-35 has proven to be unable to adapt to new threats despite being devised (and marketed) to do exactly that.
