What argument did I even make? Are you saying it's absurd that Russia's border to Ukraine is further away to the closest EU/NATO member than Cuba is to the US? Because if so, I think you need to open up a world map.
The idea that the size of Ukraine and the distance to Russia’s border through Ukraine diminishes the Russian threat. For two reasons:
1. Russia aims to either capture Ukraine outright or exert influence over it, which puts eastern EU states at grave risk. Note that Belarus, a Russian vassal, already borders the EU and was used by the Russians to launch the Ukraine invasion.
2. Russia already borders — and menaces - the EU in the Baltics.
