Lithuania, Latvia, Estonia taken together would connect the small part of Russia just south west of Lithuania and north of Poland - currently isolated from the Motherland.
Also Russia would gain more ports to operate out of.
Like the Ukraine taken as a whole gives Russia many closed mil bases, a warm water port (the Crimea).
Unmentioned as yet is Russia taking Kazakhstan to gain free access to the Baikonur Cosmodrome were all Russian manned missions are launched from as well as were its future plans to colonize the Moon will begin.
Does Borat know about this?
So now we should support US war-mongering so Russia won’t colonize the moon?
