ATM its quite possible for both. I'm going to assume WW3 will come first because if the US goes into a civil war they will be weak and that would make the US quite vulnerable.

Most likely both.
I think that America will come under domestic/terrorist attacks (more than likely a dirty bomb), which will have major economic influences.
Financially weakened, they will have no other choice but to pull their forces away from other world hot spots.
The economic strains will more than likely lead to a military state, which will lead to civil unrest. And Civil Wars (so to speak)

Russia, China will more than likely come to the aid of Middle Eastern countries (Syria, Iran etc)
Isreal will be attacked on all fronts
Europe will be thrown into chaos, and more than likely attacked from the Russian/China allied powers.

And of course at some point... there will be nuclear usage.

Something like that. LOL

But who knows... maybe aliens will land, and take us all away to be harvested for their version of fast food! :confused:

I think that the Government are buying all the ammo and tanks, while at the same time trying to disarm the citizens to do a complete takeover to get deeper into the police state. This is a war against the citizens and the terrorists are the government and the bankers/"elite" families who run the them. Remember what Hitler said, " To conquer a nation, you must first disarm its citizens."

I think the US is preparing for several million government conspiracy operations that are not permitted by them.

The world doesnt need anymore fking war.

They are definitely preparing for ww3

World War Three if North Korea doesn't calm down.

Civil War if the gun situation isn't handled correctly. (Not inputting my opinion on that.)

I think they're preparing for WW3. North Korea has been threatening us the past few weeks. They even nullified the 1953 armistice. We're basically at the brink of war but hopefully we'll be able to work things out.

Nothing will happen. It's simply a matter of fear tactics at the moment with the flexing of weapons. Remember in the Cold War the Soviet Union and the US exchanged over a thousand nuclear tests but nothing ever happened. Not only that but NK would be crazy to attack us (atm). It's estimated that they have 10 nuclear warheads. US has over 5,000 nuclear bombs. North Korea could be wiped from the map within an hour.

Nuclear warfare will be the reason for the world being completely destroyed.

And who knows? we'll have to just wait & die. Cause what are really going to do?
