So that those "sitting pretty in Zagreb" have nowhere to go, nowhere to hide, no financial support from the old Ustashi in the diaspora to hide them on the run when.if someone does come after them.
I don't see this as an either/or situation. You go after BOTH. The difference is that when it comes to the old Ustashi, you have the support of Jewish organizations who have always been far more effective at mobilizing the resources necessary to really get these bastards nailed than the Serbs alone ever have been.
The Jews know the deal and the Serbs need to stop harping on the past (60 yrs ago -ages ages ages ago).
When you go after 'both', you split your resources and weaken yourself. Go after what is fresh!
You have to plan all this out like a military op and then attack it, not rehash. That is the Serbs number one problem, they try to glorify the past as they feel it makes them stronger and prouder. All it gets them is more folk songs and myths/stories to tell their grandkids about.
That is why many Serbs in America (American-born Serbs) stay away in droves and not get involved.
That is the core reason why I'm no longer involved with the Serb PR end of it or organizational end. Their outlook is wrong and heading towards more misery with their strategy.
Screw the WW2 era, move on and go after this generations murderers and redirect all the funds to it.
Kick out the "old Serbs" and bring in the young generation to lead it. Again, that is why many many young Serbs stay away and don't want to get involved anymore.
