This is a concept beyond reach of Serbs, Chinese and RuZZians.
An aggressive NATO is bullshit. There are what 30 members. Just picture all the members in Europe with their own needs and agendas. They, like us, quarrel all the time yet they have NO NEED for troops, tanks or nukes to be placed on each other's borders. They have given up territorial expansion, now its all about economic expansion. Why cant RuZZia think like that? Easy answer is autocracy - Putin needs the country to be in a perma-state of war otherwise nice things like democracy and quality of life start corroding his hold on power.
