So what? It's like asking why the UN hasn't stopped the Russian invasion - or stopped war generally. The EU isn't a country - it's an institutionalized economic, financial, and trade federation among sovereign nations....

...that wants to act like a country. With a unified political and economic policy.

But as you're demonstrating, it's not a very well put together "country".

Heck, even in the United States - which is an actual national government and not an international federation - there are vast swathes of things that are simply not given to the federal government to do. We live in a nation built on "half-assed Federalism," so that some decisions would be made at the level of the sovereign states.

Our Federalism is far from half-assed. I don't recall the Governor of West Virgina heading out to discuss foreign policy with say, Saudi Arabia.

My point still remains - there aren't a lot of solutions to "get the job done" that remain untried.

Then there's nothing else to do except think outside the box and find other means to speed the war along towards a conclusion that kicks Putin out of Russia. If the world is unwilling or unable to inflict significant economic pain on Russia in the form of choking off the one avenue of $$$ that he's got to fund the war, then unless something breaks the deadlock then it becomes a war of attrition that favors Putin, not Zelensky.

And that's been MY point.
