Estonia considers itself a front-line state, a Nato member where its border guards stare across the Narva River at the Russian fortress of Ivangorod.
This tiny Baltic state, once a part of the Soviet Union, is convinced that once the fighting stops in Ukraine, President Vladimir Putin will turn his attention to the Baltics, looking to bring countries like Estonia back under Moscow’s control.
To help stave off that possibility, Estonia’s government has poured money and weapons into Ukraine’s war effort, donating more than 1% of its GDP to Kyiv.
The Suwałki Corridor is even less important strategically after Sweden joined NATO and forces can move through there. Its main importance right now is for reinforcing Kaliningrad, which itself is not very supportive of Mother Russia actions. So in a hypothetical invasion scenario who even knows what would happen in Kaliningrad.
