The 43-year-old oversaw a comfortable 3-1 victory, and expressed satisfaction, but remained wary of the challenges that lie ahead for the national side
The 1998 world champions broke the deadlock in the second half after a profligate first half in which Mamadou Sakho, Olivier Giroud and Yohan Cabaye failed to convert gilt-edged chances.
Etienne Capoue opened the scoring after sustained pressure from Georgy Kondratiev's side, before Paris Saint-Germain captain Christophe Jallet fortuitously scored a long-range strike, despite initially hoping for a cross.
Despite Anton Putsila reducing the deficit after initially missing from the spot, Franck Ribery secured the nation's first victory over Belarus with a well-taken third.
The former Olympique de Marseille boss was eager to stress that whilst Group I remained a difficult group, the results of the first two games remain positive.
"It was not easy today, we should've been ahead at half-time. Paradoxically, we scored when we were [performing] worse," the 43-year-old told TF1. "It is not easy to win games in this group, as we have seen with Spain who struggled against Georgia [winning 1-0 in Tbilisi earlier tonight]. Us? We have six points, we have achieved our goal.
On Jallet's first goal for les Bleus, Deschamps provided a tongue-in-cheek comment.
"Jallet has trained all week to score goals like that! I have a group of 23 players who are close to each other, I am trying to cover everybody, and those who have played today have proven their place in the squad," he said.
France's next World Cup qualifier is against Spain on October 16.
