Perhaps they did not get the memo, Obama is no longer President... I think President Trump would handle any hostile action a little differently then just rolling over exposing his belly.
Well...
Obama exposed his butt
People forget or never knew that towards the end of the stupid Obama-Iran Nuclear Agreement, the Iranians intentionally sank a mock up scale US carrier. This was done during an Iranian military exercise to show that Iran means what it says to the Obama administration. After President Obama and John Kerry wet themselves, the deal was signed by a knee-trembling US administration.
