About pics of military lorries and APCs on trains that some lunatics posted on Twitter. aka that Russia is moving their forces to Poland-Russia border. Russia wouldn't mobilize their forces to the border with Poland, there is no need for that (for all that missed the point - there is no Poland-Russia border anymore)
And that speech from Polish PM doesn't surprise me at all.
The Kaliningrad Oblast is part of Russian Federation and as such Poland and Russia do share a common border.
Apparently it took more than 7 months for the French and British to cross the Maginot Line
? French troops conducted forays into the Saar already in September 1939. During the 1940 campaign there was no large scale movement past the MG line, only delaying forces.
