How do you determine if an American overseas poses an imminent threat? Is he walking around with a back pack of viable explosives? What was the Yemen cleric´s imminent threat?

Behind every leftist pacifist mask lurks a crouching dictator´s mind, ready to pounce when finally in a position of power.

Eggggzackly, #2, look no further than the Oval Office.

As long as Obama gets to define who are or are not terrorists, and "imminent threat" is undefined, this is a direct threat to US citizens.
Obama decides that CAIR, ADA, and other muslim front organizations are not terrorist, and provides direct monetary and military weapons support to the Muslim Brotherhood, which is designated as a terrorist organization.

Can we not envision that Obama may define the NRA and Tea Part as terrorist organization at some future time, and reply drones? Certainly for surveillance, but possibly for attack? Do any of us think the Leftmedia will hold Obama accountable if he does?

#4 “...

All it will take is one idiot who happens to be a NRA or Tea Party member to go nuts at a school or mall. And if one can’t be found maybe one can be manufactured.

What difference does it make?

They already have the power to kill millions of Americans through ObamaCare.

Wake up America!!

Obama is just like LBJ, who used to spread out the maps of North Vietnam on the floor of the Oval Office to personally pick the bombing targets. LBJ once bragged that there wasn´t a single outhouse in Vietnam that couldn´t be bombed without his approval. What could possibly be easier for a tyrant than to sit back in the easy chair and order bad things on people with no ramification?

O´s deliberate obfuscation on the topic of drones is nothing more than an attempt to intimidate Americans.

He wants us to fear him.

NRA and tea party, think twice if olanning trip outside the USA.

A pimply faced punk sitting in his mother´s basement playing video games. Running up his score to the highest level. To him, a terrorist is anyone he deems to be and he, personally, will take them out. Score a trillion for that one, another billion for this one. Friends of Mr. Cairo are not to be touched. If one should happen to be a Tea Party member, that equals bonus points of 20 million. And unborn infants, that is another 250,000

It is not just Droning U.S. citizens abroad in other countries, it is here at home as well. The other countries, Russia, China, North Korea are waiting until Obama takes ALL of our guns away from us, then they will pounce on us like cat on a mouse.

From the article:
. . . a targeted U.S. citizen has to have recently been involved in terrorist activities and pose "an imminent threat of violent attack against the United States."

In my opinion, the Jihadist-in-Chief is himself an imminent threat of violent attack against the United States.
