The problem with Marine Le Pen and her party, and also with most European Right-wing movements, is that they're faux rightists. They are more akin to stupid "nationalism" than they are to American Patriotism, and, consequently, they have no commitment to the values that have made countries like the United States excellent. Le Pen is a fan-girl of Vladimir Putin, and is likely a useful idiot or an outright traitor. She'll pull France out of NATO if she could, and curse America as Russian tanks roll into Paris.
France is not the US. They have a whole different history than we do and different values.
