Under pressure to effectively fix the French economy, President Francois Hollande recently won some acclaims on the security front.

During a sudden visit to Charles de Gaulle airport on Thursday morning, Hollande promised to French voters the highest vigilance against terrorist threats, stressing that citizens and public interests are safe thanks to reinforced safety measures.

"There are threats that are particularly targeting France... (However), everything was in place so that the safety of French is guaranteed, and it is", assured the president.

A day after, the Socialist top official confirmed the release of seven French hostages, including four children after two months of captivity by an Islamist cell in Cameroon.

Expressing firmness and determination, Hollande said "this is an immense relief. This will redouble our determination to free the hostages who remain" in the Sahel region.

The French president got to Paris' Orly airport on Saturday morning to welcome the freed French family. Their return is no doubt good news for Hollande amid all the economic hardships.

"For the moment, the hostages' release could be considered as a political success of Hollande in this context of disastrous news," said Thierry Arnaud, head of political division at BFMTV news channel.

"Nevertheless, there will certainly not be a lasting positive political effect because after the joy people will quickly focus again on their main concerns which are economic crisis and unemployment," he added.

The Socialist president had set himself a two-year deadline to turn around the stalled economy and reverse the rise in unemployment, a not so easy task amid the generally gloomy economic environment.

"We can not overestimate the impact of captives' liberation or of a focus on security. This may improve his structural image but not his economic achievements," Eric Bonnet, analyst at BVA, marketing and opinion research agency, told Xinhua.

"There is a reality which remains. It's that of high joblessness and feeble economy and Hollande would be only judged on that," he added.
