When the $21 Trillion EU puts their big boy pants on and form their own army, they can have agency (Serbia, Bosnia, Kosovo, Libya, Syria, etc, etc).
Until then, the 900# red white & blue gorilla of NATO is driving. Folks don’t like it? Well, time to stop whistling “The Yanks Are Coming” every time they want to tussle with their neighborhood.
Surely that was a decision to be made by the relevant countries themselves and not Bush Sr of the United States.
