It seems like France stands out among terrorist attacks in the news. Is it because they are more likely to be critical of Muslim culture than other European nations? Is it because there is a security failure allowing terrorist to come in and organize better?
Mali(Chad, Mauritania, Niger) may not officially be French anymore, but let’s not forget French soldiers spent a good decade at war with Jihadist groups in the Sahel, which made them extremely unpopular with a lot of people.
France has also been quite interventionist in other countries in the region, like Cote d’Ivoire.
Also, technically speaking, France doen have a handful of colonial regions, 2 million people live in them.
Technically speaking, those regions (which I mentioned above) are not colonies. Of course one could argue they are in all but name (and I would agree), but they have nothing to do with any case of terrorism on the mainland, which is what the above poster was saying.
As to the rest of your post I agree with your point, but those are not colonies (the OP was deleted since but it said that terrorism happens because France still has colonies, which is bullshit on many levels).
