Yugoslavia wasn't weak in 1999. It had formidable defenses at the time. You think that USAF struck Yugoslavia with 21st century tech? These type of arguments are lame and they show that you have not studied history properly.Against weak Serbia without Air Force and with outdated AD Systems
go and enter Russian airspace and attack on Moscow
then see what will happen with F-35s
Israel can attack on only weak Syria .... nothing else
Ukraine have demonstrated the capability to hit Moscow and even Russian military bases. Ukraine have also conducted commando raids deep inside Russia. Wake up, mate.
