Is There a Legitimate Authority to Declare War?

i don't believe it is any third party has the right to declare the situation as a state of world. So, legitimate authority that needs to be clearly defined. In such a scynario yon, things also get con ated men nowand state actives are involved. But again, realityis the general defirit. And we'll discuss mood on this lateer. but i just wanted to point out, if ther non state kind of actors are involved, then, yo, situation, we con indifferent. You absolutely agree, you know. It's not for them to declare what the situation is. It calls for immediate action by the key actors that are involved"
