And the world gets more complicated
From the article:
Baltics - Lithuania, Latvia, and Estonia - have all expressed concern about Russia. NATO-led battle groups have been deployed to each country. Lithuania has hosted 150 US troops since 2014, and in mid-2017 the country’s president requested a permanent US presence “to not only deter but to defend” against possible threats.
A particularly worrying scenario for some in the region is Moscow closing the Suwalki Gap, a 60-mile-long section of the Poland-Lithuania border between Belarus, a Russian ally, and Kaliningrad, a Russian exclave on the Baltic Sea. Such a move would cut off the Baltics from the rest of Europe.
