Spy Today, Die Tomorrow (1967)

Millionaire Baretti pays a gang to rob an atomic bomb from an American silo, and then blackmails the USA Government for a huge amount of money. German secret service (BND) agent 'Dynamite' will use his fists, guns and more in a violent bomb chase. In the end, Barelli's accomplices are dead or arrested, but he escapes unmolested, while Mr. Dynamite spends time in a Mediterranean resort with a lovely woman.
