"We need to think about more durable solutions" than solely sending European peacekeepers to Ukraine, Italian Prime Minister Giorgia Meloni said on the sidelines of the EU leaders' meeting in Brussels. "It’s a different thing than entering NATO, but it implies extending the coverage that NATO countries have also to Ukraine," she added.
It technically only says all parties will take what actions they deem necessary after an attack. Which could just be sending weapons similar to what they’ve been doing. The power of NATO comes from the military integration and economic mixing such that the incentives are aligned for one country to defend the others, not just the words on the page of the treaty.
