Yeah, still wouldn't change anything, our troops are a shambles and that's not due to sheer numbers of manpower. It lacks everything the military needs. Funding, Equipment, qualified manpower, pride, social acceptance, organization, leadership, you get the hang.
It's obviously not a completely shaped plan, but there'd be lots of possibilities considering the amount of variables.
If anything, a centrally european commanded army could prevent single european countries from creating a mess. I stand by what I said. The US are not a reliable partner anymore. At the very latest Trump has shown that very drastically. If the US isn't ready for a black female president when Biden's terms end, only god knows which idiot they'll finde to do the job. Eric Trump? Na man, I trust my european neighbors. I really do. It's highly complicated and it's far from happening, but it would be my vision for Europe, as I think the time of national states for Europe has come to an end. We need each other - not just economically.
