I think so. What is interesting to me is that sending in thousands of anti-tank missiles to assist Ukraine is no longer considered an act of war. I suppose Russia would rightly be hesitant to declare war on the US and NATO regardless of our materiel aid.
“Non participants” “sell” weapons into wars all the time. It’s never been considered an act of war.
We didn't declare war on China when they tossed 200,000 troops into Korea, and just about every scrap of hardware the North Vietnamese had came from China and/or Russia. Has the United State faced an adversary in the last 70 years that wasn't supplied by Russia or China?
The Russians and the Chinese armed the N. Vietnamese and the Viet Cong during the Vietnam War.
Apparently it wasn't considered an act of war back then and thus the same now.
