Dear Mr Trump,
thank you for your concern.
A man has indeed attacked a soldier with two machetes this morning in Paris.
It wasn't in the Louvre Museum, it was in the Carrousel du Louvre, which is a mall. (Less symbolic than what you're implying.)
He didn't attack any tourist (or french people -apart from the soldier- either, by the way, thank you again for your concern) and he was instantly attacked back by another soldier, and wounded.
The crowd has been kept inside after that by order of the army for security reasons, but not for any kind of hostage situation. (Your tweet is -voluntarily?- ambiguous)
France is not on edge again, at all. I learnt about the attack 10 hours after it happened (even though it was in the media earlier), and I spent 1h30 in another mall in Paris at lunch today without any kind of military reinforcement (I mean, just the usual since Charlie Hebdo or nov 2015 attacks).
Oh and by the way, the man is from Egypt, you know, the country you didn't ban from entering the US (because of your personnal affairs?)
Again, thank you for your concern, but don't use France as an excuse for your arseholery. You're the one encouraging fear with your distortion of truth.
Regards,
Egie Wild
