Outer Limits / Twilight Zone episode
Can't remember if it's The Outer Limits or The Twilight Zone so bear with me. I'm thinking of an episode where numerous people are chosen to destroy the earth if need be. They are in isolation and have no idea what is going on outside. Now these people aren't all in the same room, but they are connected by cameras. They are in different locations around the world. The reason they would need to destroy the earth is because if there is an alien invasion. Well, one by one the people start to die and then when only one person is left and he is about to destroy the earth, the President comes on and tells him not to, but it turns out that the president is being controlled by an alien.
If you know it, please tell me the show and episode number.
Thanks in advance!!
