I found this on Reddit and I read the whole thing, I thought it was interesting.
The author argues in favour of greater European independence on defence (and less dependence on the US). The article is a year old but I think it’s still relevant.
The author is apparently a journalist with France 24, a French state-owned media company, so you could say that makes him biased in favour of the French position. But I think he still makes valid points.
Qualified majority on foreign policy matters by the Council and a simple majority from the parliament. Also the option to defend the EU called out by the Commission to be able to act quickly.
