Absurd and silly election time exageration. We are not at war with Russia. 200 miles is international waters. It was a friendly gesture and would be expected to be reciprocated. If a US sub was off the coast of Russia and they refused safe harbor and there was an accident what would we say? By calling it an “attack sub” it is made to sound incendiary, but it isn’t.
It is an attack sub, meant to attack other subs and ships, as opposed to a missile boomer. It’s not intended to be incendiary, just descriptive. Attacking things is what warships do and submarines are definitely at the pointy end of the spear.
There are protocols about the distance missile boomers are supposed to keep off shore, a gentleman’s agreement. Their isn’t any evidence that they were in distress. When a Russian freighter was in Boston Harbor, we were not allowed to test certain waveforms for a Navy radar at a land site twenty five miles away. Every Russian ship is an intelligence platform.
Uh...a Sierra-2 IS an attack sub.
The Russians have figured out that they can cruise the U.S. coastline with impunity.
