I watched the entire debate last night, as it was streamed by most of the French MSM websites.
I do hope the French people will think twice before they give Mrs. Royal the keys to the nuclear suitcase.

Defense matters were not discussed at all, and European and foreign affairs got very little attention, a few minutes at the end of a two and a half hours confrontation, that was mostly dedicated to economic and social issues such as the national debt and the retirement funds crisis.
Sarkozy did not miss the mandatory lip service to the prevailing anti-American screed, when he reminded the audience that while he opposes Turkey's accession to the EU, the US is pushing for it in order to empty the European idea of meaning and substance, aptly reminding the voters that Europe should not have a boundary with Syria, Iraq and Iran, and has no interest in acquiring a Kurdish problem.
The candidates did not even make a passing mention of the global jihad, and the question of immigration did not elicit much of an argument between them. Sarkozy, however, managed to subtly convey the perception that his opponent would be more likely than he is to throw the gates open to the Barbarians.
Segolene did not make any clear statement on Europe, Turkey, or immigration, and gave the impression that she does not really have a position or does not care about these issues.
It is to be noted that both candidates made firm statements against Iran acquiring nukes, any nukes, but none of them even hinted at the policy they would implement in order to achieve that.

I know I am biased by the situation of the country where I live, but I would like to ask the French voters one question: which of the candidates do you see as more suitable to lead you, and safely get you through wartime?

sarkozy would be more suitable to lead france during wartime
But royal would be more suitable to avoid wartime.

If sarkozy was president in 2003, french soldiers would be in irak. Relations with the US would be better for sure, but i'm not convinced that would justify being implied in this mess.
