Apart from the Black Sea, Russia has a single ice-free port kaliningrad in the Baltic.
https://en.wikipedia.org/wiki/Kaliningrad
In 2007 Russia warned that if US-controlled defence systems were deployed in Poland, then nuclear missiles would be deployed in Kaliningrad to defeat that plan. In 2008 Russia said that missiles inKaliningrad were likely . These plans were suspended in 2009. So it looks like there soon might again be nuclear armed cruise missiles in the Baltic. And since Kaliningrad is sovereign Russian territory there is nothing the West whatsoever can do about it . So Russia will park more tanks on our lawn due to dumbass hostile manoeuvering by the thick American neocons who run NATO. All of this could be so easily avoided with a tiny amount of common sense.
Yes, this so they can hit children's hospitals more easily.
