It is an actual Russian “divide and conquer” troll. A “warm water port” is exactly how you string that sentence together in Russian. A Texan would first of all call it a harbor (port is the word for it in Russian, so likely a direct translation), secondly wouldn’t mention that at all, since an “ice port” isn’t even a thing anywhere in the US, except for Alaska, and having an ice free one is nothing to brag about. In Russia it is a big deal and is a matter of national pride, hence the Crimea takeover. It’s more than just land to them.
