Sub-Mariner #4

The U.S. government is after Namor-public enemy #1! A terrorist attack perpetrated by an Atlantean sleeper cell has killed 800 innocent civilians...but who gave the order? While the Sub-Mariner scours the surface for answers, Tony Stark, Director of S.H.I.E.L.D., tries to prevent a seemingly inevitable war between Atlantis and the surface world...but even Iron Man can't stop the government from unleashing their secret weapon on Namor-the Thunderbolts! With extreme prejudice!
