@Sviatogor USA doesn`t need any military base in Balkans, they have their own state, Kosovo. Just like RF have intelligence-spy center in Niš.
USA offered us, in several occasions, their old F-16, we rejected them. Israel too. Also we rejected USA transport helicopters as unfit for our conditions. On other hand we bought 16 Kiowa helicopters.
Croatia have small but respective weapon manufacturing industry. The only branch of industry which is on constant rise.
Of course Croatia isn`t able to buy or produce modern fighter. But, the new russian fighter is also expensive just as any modern NATO fighter.
