Isn't it like the playing domino effect? You first arrange dominoes, and in convenient moment, only have to push one. Then, watch them do the job by themselves.
The result?
Serbia with no president, no PM, no constitution, no money, "shocked and awed" population, paralysed at the right moment.
It is not important who pulled the triggers. What matters is who gained.
Both Serbian Government and NATO were swift to blame "criminals" for assasination. Why jumping to the conclusion before investigation is done?
The conclusion should be left to Serbian Warren Commision, of course.
