"United States under the S.O.P.A. law should go to jail for using a name not belonging to it...or pay us the copyright."

I don't get your point, The first picture is the United States of America not simply AMERICA; which is a country on the continent of North America which itself is part of The Americas (the second picture) all of which were named after Amerigo Vespucci who was Italian. Furthermore the word America is not Copyrighted.

That's like saying the Republic of South Africa should pay a copyright to Africa...
