I guess if Reapers are capable of conducting strikes in Venezuela their air defences must non-existent.
decapitation strike not only come from hard physical strike , if any nation dare to do that alone they gonna either end up like russia early 2022 or worst , even if they manage to win somehow that gonna be very costly victory
large part of it come from non-physical effort before the real strike happen . sactions , economic attack , blockable , sabotage ....etc destroy the target country economy , ability to make money , trash population quality of life to the point they basically low-key welcome invader , ready to sell out their boss/gov offical/president/leader once invader offer a better deal
US will not able to captured maduro easy like that if they don't heavily saction , sabotage venezuela to hell , ruin the country economy , trash the population quality of life so much for years before launching final strike , same as what they did with iraq
you can give venezuela military most advantage air-defense missile in world ....still it doesn't matter if venezuela military have no interest to fight
