You will have to wait for 18 more years to get a (short lived) II Republic until 1852, and 40 years for a stable republican regime in France. ;-)

I do hope that the syrian crisis is as much in your scope as the israelo-palestinian conflict, because it is a source of concern to french secret services that french arabs may convince themselves that they would be fulfilling God's commands by going to Syria and Iraq to slaughter civilians in the name of the Mahdi ₍₁₎... and then get back to France to do the same at home.
