A few observations.
First of all, someone tell the Washington Post that the USS invincible won't be built until sometime in the 24th century.
Or were they referring to the ship from 1918?
It is the USNS
Invincible. It is an unarmed or lightly armed tracking ship.
Secondly, leave the analysis to the analysts. My brother-in-law is a retired US Naval Intelligence officer. He speaks fluent Arabic (not sure about Farsi). He was stationed in Cyprus, Spain, and Maryland among other places. He picks up things about Iran's behavior that you would not even notice. For example, UN resolution 2231 bars Iran from testing ballistic missiles that are capable of carrying nuclear weapons. A UN panel has said it considered ballistic missiles capable of delivering nuclear weapons to be those that can deliver at least a 500-kg (1,102-pound) payload within a range of at least 300 km (185 miles). Iran will always be saber rattling. They will always push the limits to seem tough. Notice that the most recent missile they allegedly fired, has a max of 300 km, and they made a point of saying it went 250 km. Those distances are not just a coincidence. They wanted to push the limits, without actually violating them...Something that didn't bother them before Trump "put them on notice."
Thirdly, before Iran was "put on notice" by the Trump administration, they fired off a MRBM (medium range ballistic missile) then had another on the pad but chickened out and pulled it.
Also, they were charging US ships and getting close enough to elicit warning shots from the Americans. Now, in the Thursday episode, there were no shots fired, as the Iranian ship (on a parallel course) must not have closed that threateningly on the Invicible (and its three British escorts). In the Saturday incident, they only came to within 600 yards, and then stopped. Supposedly the Invincible then changed direction.http://www.ibtimes.com/iran-preparing-w ... ck-2503100
Interestingly, the Iranian version says ...the USNS Invincible, a tracking ship accompanied by a group of British ships, was crossing the Hormuz Strait area, when it “changed direction from the international route toward the boats of the Iranian Revolutionary Guard Corps (IRGC) navy.”
“In an unprofessional move and in a maneuver accompanied by warnings, it approached our vessels at a distance of 550 meters,” Lieutenant Commander Mahdi Hashemi, in command of Zolfaqar battle flotilla, said, as cited by Tasnim news agency.
“Such provocations can have irreversible consequences,” Hashemi said, according to the Tehran Times.
Iranian President Hassan Rouhani also issued a warning..."https://www.rt.com/news/379898-iran-us- ... fessional/
