Besides, does the US even declare war on anything anymore? No, it’s mere ‘intervention’, ‘operation’ or ‘policing action’ here and there as they label it, they didn’t declare it in Korea, nor Vietnam, nor Iraq, nor Afghanistan, yet that didn’t stop them from making a war here and there. Why shouldn’t it be with this country or another?

It’s like "it’s not champagne if it wasn’t declared to be from the champagne region, otherwise, it’s sparkling wine’.
