Under any circumstance. I wasn't referring to this baloon.
You said,
So much for your "open skies" approach when a weapon disguised as a surveillance craft shows up.
So you are now admitting there is no evidence this balloon was carrying weapons.
At least you are learning.
I'm leaning toward intentional provocation. We can track softball sized objects in orbit. They would surely realize we could track something the size of 3 city buses.
And no, this doesn't change my view on Open Skies. I believe countries constantly surveilling each other in a non-harmful manner creates a more stable peace. Nothing that has occurred changes my opinion on that.
