@ErikJonker@Geopolitics I've been advocating for a NATO presence in western Ukraine since Day 1.
Pick a distance from the frontline well out of artillery and SHORAD range. Draw a line in Ukraine. Literally if you need to, even visible from space if one must. NATO mans the sky and ground behind the line, Ukraine in front of it. All of Ukraine's resources in the rear now go to the front, and Russia knows that even in the best case it can't advance very far in Ukraine.
