The German Bild-Zeitung has implicitly confirmed the assessment that Russia has taken control of the Baltic region, mainly in being able to prevent larger NATO military deployment (by ship or transport planes). This in practice means that in the case of a Russian military aggression the Baltic region will have to defend without the chance of a larger NATO-backup. It is unclear how the realities on the ground will affect he planned deployment of NATO-troops to the Baltic region starting from January 2017.
Additionally, Retired US General Jack Keane found the there was a “possibility of challenging NATO with a military hybrid occupation similar to eastern Ukraine”. Some have estimated the troop number being massed in Kaliningrad to be at some 225.000 Russian troops.
