Yes.2) Does the average US resident know that the mutations leading to mutants were created by humans as weapons in government labs?
They know that they went rogue thanks to the Stryker and there are some that agree with him.3) What does the average US resident know about the origin of the Nimrod Sentinels or what caused them to attack humans?
Not that he was a mutant, but they know that he caused the attack.4) Does the average US resident know anything about the role of William Stryker, Jr., in the attack of the Nimrod Sentinels or that he was a mutant?
They know about the virus, as it was heavily publicised, but there has been little mention of Tian in all the Game of Thrones-y stuff so my guess is that only SHIELD and the Ultimates are fully aware of it outside Tian itself. Edit: Or apparently they do, no one has been talking that much about it's status in the book itself though.5) Does the average US resident know about the new regime in Tian, the powers that its people have developed, or that they are welcoming mutants seeking asylum? Is the average resident aware of the virus that previous to Divided We Fall disabled mutant genes in many? I'm assuming it is known the numbers of powered mutants are now less than the number of giant pandas in captivity in today's world.
