During the Gulf War (1991), the US Navy and the US Marine Corps had assembled consequent naval and amphibious forces. Some of them (including the battleship Iowa) were attacked by Iraqi antiship missiles.
Those forces seemed to indicate that an amphibious attack was in preparation, and some Iraqi units were distracted from the Koweit-Saudi Arabia border to protect the coastline near Bassora.
However, this attack never got real, and the real attack was a massive land and air campaign. Only litte fights saw the Arabic navies of the coalition fight Iraqi navy.
Alone, without the massive deployment of the coalition in Saudi Arabia, would an amphibious attack stand a chance against the Iraqi army? Criterias: Stand a chance means to land troops, defeat counterattacks and free the Kuwait territory (at least). An air campaign could be made from the US carriers, a very long one if needed.
