We always have been considered a threat to them. Deep down there is a lot of resentment and dislike for this country in Europe. Why do you think there is an EU? It’s not purely economic they had always planned to have the largest economy and a military to challenge ours.
Why do you think they are allowing so many military age men into Europe? Military age men who hate the US and Israel. Think about it.
They sure can expand the ranks of their Légion Étrangère in a hurry if they felt like it.
And there’s also the Bundeswehr taking over the command of parts of militaries of countries like the Netherlands, Slovenia, Croatia and a few others. They’ve got some bad cards up their sleeves.
