You still haven’t addressed my one and only point.
We will not suddenly have a declaration of war one day.
It will be small things, then bigger things, then bigger things, until it escalates into full-scale shooting war.
We may already be in the beginnings of it.
You said:

That, sir, is the point where there will be a formal declaration. Perhaps not a Congressional declaration, Congress doesn't do those anymore*, but a presidential one.
*IIRC, war crimes trials require a formal declaration of war...
