What implied threat are you referring to? Iran's laughable “fleet”?
Perhaps you never considered that The Soviets, and now Russia, along with China, have previously had nuclear tipped missiles in subs patrolling off our coast, and it's almost %100 likely they also have them off of our coasts right this minute. That's the nature of the world we've lived in for over 60 years now in the case of Russia, and more recently China.
I don't hear people constantly pissing and moaning about that reality on this board, yet you have Iran float a couple of ships over to our neighborhood and all of a sudden nuke's will be raining down on our capitol or EMP bursts are imminent!
Honestly, get a grip!
Russia has an interest in staying alive.
China has an interest in keeping it’s communist framework and enough workers alive to continue on.
Iran is looking for a way to get some asshole out of a well and they’ll do whatever it takes.
China and Russia at least are ruled by sane people. Iran is ruled by mad Islamic dogs who wouldn’t think twice about trying something like a EMP or a small Tact Nuke.
Islamics think there are virgins waiting for them if they die killing infidels.
If we had a leader with a damn spine, there would be a squadron of warships blocking their way. And if anyone cried about it would tell them to piss up a rope.
