So the fierce wars with Vietnam and the Soviet Union in 1960s, 1970s and 1980s are not counted. But the US "experiences" with Iraq, Afghanistan, Serbia and Venezuela are counted.
Same with how Western weapons are "proven" in battle. They are "proven" in bombing and firing missiles to innocent people, or primitive guerillas (which even a WWII aircraft can do). When being used in real wars like in Ukraine, how "proven" they are?.
The Iron Dome is one clear example. Sky-high evaluation by Western media before war, almost useless in real wars, even against rudimentary rockets made from water pipes and fertilizers by Gaza militants. Not to mention they fire hundred of thousand dollar missile to prevent a several-thousand dollar rocket. Without the continuous pumping money by the US and the West, how long Israel can withstand the missile attack from Iran?
