Guns vs missiles is a bad example (missiles clearly won decades ago). It's more about eg. wanting to use a locally developed missile instead of using one of the US approved missiles (because missiles have to be tested, integrated, and approved to be used on an aircraft before you can actually use them, which can take years even before accounting for politics.) The MDBA Meteor (European AMRAAM competitor, generally viewed as the best beyond visual range air to air missile (BVRAAM) currently) has been in service since 2016, but won't work on F-35s until ~2026. For comparison, it only took ~1.5 years to integrate the Meteor on UK Eurofighters.
