It clearly connects the two, and used to be a land border, but now it's submerged, which destroys all ways of traveling their by foot or car. If we are going by stuff that's under the water, we would have countries that say they border Austrailia. The border that I'm talking about is a land border where you have to cross some sort of checkpoints to be let into the nation. I'm sure they have them on the shore, but it's just not the same, so Russia doesn't really border America per se, just in the sense of "it's close, but too far away."
