Iran really testing the US navy

Can you please explain this for me? Are you saying do we have the people to go take over iran because that is comical at best. We could take over iran with a few thousand guys not even going into their soil. The troops are only needed to secure the area for the restructure. I hope you do not believe that the US military would be in any way shape or form threatened by Iran if so you are very misinformed of our capabilities to say the least.
