Only on wickedfire are military exercises an act of war.
Seriously?
Read "War Is A Racket", written in 1935 by Major General Smedley Butler, the most decorated Marine in history at the time of his death, still one of the most decorated of all time. He predicts the beginning of WW2 with scary accuracy in that book.
It's a 10 minute read, well worth it.
One notable quote...
First of all, they let it be known that America is menaced by a great naval power. Almost any day, these admirals will tell you, the great fleet of this supposed enemy will strike suddenly and annihilate 125,000,000 people. Just like that. Then they begin to cry for a larger navy. For what? To fight the enemy? Oh my, no. Oh, no. For defense purposes only.
Then, incidentally, they announce maneuvers in the Pacific. For defense. Uh, huh.
The Pacific is a great big ocean. We have a tremendous coastline on the Pacific. Will the maneuvers be off the coast, two or three hundred miles? Oh, no. The maneuvers will be two thousand, yes, perhaps even thirty-five hundred miles, off the coast.
The Japanese, a proud people, of course will be pleased beyond expression to see the united States fleet so close to Nippon's shores. Even as pleased as would be the residents of California were they to dimly discern through the morning mist, the Japanese fleet playing at war games off Los Angeles.

War Is A Racket, by Major General Smedley Butler, 1935
So no, it's not just WickedFire.
Sanctions and "military exercises" that take place at a country's front door have always been provocations that lead to war. And yes, I'd say that sanctions can in almost all cases be defined as an act of war.
But what did Major General Butler know?
It's not like a Major General knows shit about what's really going on.
Try visiting a country impacted by international sanctions sometime. I was in Iraq in 2004. The sanctions killed a lot more people than the war did, especially in regards to women and children.
If shit does go down we'll have bigger problems on our hands than just North Korea.
