@Quix Quix, you should worry about N. Korea instead of outer space aliens.
"United States intelligence officials believe North Korea has mini nuclear warheads that can be delivered via its intercontinental ballistic missiles."
The report I saw/read from our Intel agencies, the Pentagon included, said N. Korea, in a few months, will have ICBMs that will reach Washington, D.C., and the east coast. And, they may have as many as 60 nuke bombs now.
Sanctions will not stop N. Korea from sending nukes to this country and they can do it now, hitting as far east as Illinois, according to our people, not their people.
This info. has come down very fast. It appears to me our intel groups/Pentagon had to finally tell us the truth about N. Korea as an attack could happen at any time, especially since these new sanctions have come about, enraging the nut case who can send bombs whenever he wants.
