Well, They took care about other ruthless dictators. And they had like 10:1 military advantage. They even had some friends in Yugoslavia (see one of the previous posts)
They could run him over pretty easily!
I always felt that they sort of needed an enemy, so they could shoot people in their countries, and blame them on Tito? Kind of having Tito as a straw man. But, I do not know.
Now there is another theory that I heard floated, and that was it was all Kabuki Theater, with Tito made to look to be independent from Moscow, so as to gain favor with the “non-aligned” world, remember he was a Comintern agent from way back.
I believe Tito’s funeral still holds the records for the most Heads of State who attended.
