This is good:
In late 2017 Sweden decided to upgrade its air defenses with the American Patriot system. For decades Sweden had been using the older Hawk system and was in the midst of upgrading Hawk when it was realized that even a much improved Hawk could not deal with all the new weapons Russia was developing.
My view on defending the Baltic states from Russian aggression is to plan to survive the Russian invasion by preserving NATO's most ready heavy forces, holding the line around the Polish-Lithuanian border, capturing Kaliningrad, and then driving north after mobilizing to liberate the Baltic states which are resisting Russian occupation with the assistance of NATO special forces and long-range firepower.
Swedish territory combined with air defense weapons give NATO depth to control the Baltic Sea despite a potential Russian conquest of Estonia, Latvia, and at least part of Lithuania; which will allow NATO to prepare for the liberation of the Baltic NATO states.
Remember, Sweden has an interest in having a friendly shore on the other side of the Baltic Sea. Russia is not a friendly state for Sweden any more than Russia is friendly to America and NATO under Putin.
