This is how it goes. Serbs in general are aganist NATO and most of them does not rly have particulary high opinion of US, HOWEVER. When you live in country where finding half decent job is basically impossible unless you are in some major political party or non government organization you are required to change your opinion at least in public to suit their needs.
So its like this, guys from party come to your house, they say how they will find a job for your son if you vote for them, if you sign whatever petitions they make, if you go to their promo gatherings etc. Basically you have to dance following the music they play or you get shit. Young ppl love getting job in non-goverment organisations, and we know who mainly funds them, so its same story there. Basically they are abusing low income, unemployment and low living standards in general.
