The White House told Iran to "refrain from further missile tests if they truly seek to gain the trust of the world."...
...means in plain english, "Don't antagonize us and by and large, we are the World!"
"In anyway, we have all the rights in the world to test everything, including the missiles!"

The arrogance of the US Govt. is the reason for more than half the anger and anguish of the world!
{It does not mean that what Iran has done is correct!}
