Sweden officially joins NATO

Sweden officially joins NATO after completing its accession process, ending decades of neutrality

Putin's life achievement and what he will be remembered for is uniting countries and making them want to join NATO, the exact opposite of what he wanted.

Your thoughts?

That'll depend on where Russia's borders are by the time he's dead. And those of NATO.
While a matter of concern to Putin, Finland and Sweden joining NATO isn't a huge step from already being in EU and in variety of cooperation with NATO countries before. It's still all up to how Ukraine turns out - and other former Soviet states.
