Oh, dude, DEFCON 5 is like the lowest level of readiness, so it's basically like the military saying, "Chill, we're good." The US has totally been at DEFCON 5 before because it's like the default setting when nothing's going down. It's like being on standby but also not really caring.

No, the United States has never been at DEFCON 5. The DEFCON (Defense Readiness Condition) scale ranges from 5 (the lowest state of readiness) to 1 (the highest state of readiness). DEFCON 5 indicates normal peacetime readiness, while DEFCON 1 signifies imminent nuclear war. The US has never reached DEFCON 1 either, but has been at higher readiness levels during times of heightened tension, such as the Cuban Missile Crisis in 1962.
Oh, what a lovely question! You see, at DEFCON 5, everything is peaceful and calm, like a gentle breeze on a sunny day. The United States has been at DEFCON 5 many times, when there are no current threats or tensions requiring increased military readiness. It's a time to appreciate the beauty of peace and harmony in our world.
Defcon has 5 levels.
Defcon 5 is the lowest, the normal setting, so yes the US have been at D5
Defcon 4 is above normal, so during a war like Afghan and Iraq, D4 would have been activated
Defcon 3 is where we start to worry. This is the one during critical points during war. Just to put into perspective, D4 was standard setting for ICBM sites during the Cold War.
Defcon 2 is not good at all. There has been only 1 point where D2 was called and that was Cuban Missile Crisis, where the world was hours away from a MAD war.
Defcon 1 is the worst. At this point, say goodbye, nuclear war is minutes away. D1 had never been called and I hope it never is.
Defcon details remain classified and criteria for their setting has changed over the years.
DEFCON, or defense readiness condition, is not a national status for the United States. Different branches of the military can be under different DEFCON levels. DEFCON levels are controlled by the President and the Secretary of Defense when ordering to raise or lower the level across all US Armed Forces; however, branch leaders and administration can also individually raise or lower DEFCON levels of their respective branches. DEFCON 2 is the second-highest level of alert readiness for the United States Armed Forces, and conjointly describes an emergency defense situation in which nuclear war is near. The only time DEFCON 2 was ever raised was during the Cuban Missile Crisis in October 1962. The Strategic Air Command (SAC) was ordered to DEFCON 2 alertness by their command headquarters on 26 October 1962, while the rest of the armed forces stayed at DEFCON 3.
The Spanish-American War of 1898, lasted about 5 months.
Nobody has ever counted and nobody will ever tell.
Yes.
The longest war the United States ever entered was the Vietnam War.
