In the contest of strong wills, Tito held his ground. He had refused to be intimidated by the infinitely more powerful Soviet Union and had shown personal as well as political courage. The Soviet press poured vitriol on him. There were even Soviet attempts to assassinate him. But Tito would not bow to Stalin's bullying. Stalin kept a note from Tito in his desk drawer, found only after his death: 'If you don't stop sending killers, I'll send one to Moscow, and I won't have to send a second.'
