The problem with calling this a war is that the right-wing press are calling this a war. This is not an existential threat to us in the way, say, WW2 was to the Soviet Union or to the UK once we had engaged militarily. We could withdraw from bombing campaigns in the middle east tomorrow and see almost no immediate detrimental domestic repercussions. That is probably a sign that this is not so much a war but something else. If it was domestic we would call it a massacre.
The more we go down the road of annihilation, the more costly that peace process will be and the more people will die purely for war. That includes our own.
WW2 was an existential threat to the Soviet Union. It was so existential that this became the largest part of the identity of Russians.
But WW2 was not an existential threat to UK. UK could have exited from the war at any time. No battle took place on the soil of UK mainland.
I am not saying the people in UK did not suffer - they just did not suffer comparably to the people in the middle of the conflict. In a way the war was rather distant to the people living in UK.
Well, that's because the battle eventually took place in (mostly) France. But it's not as if that battle would not have eventually happened in the UK if the Germans had managed to gain air supremacy over the UK or if they had managed to pull a reverse Normandy. The UK could not have exited from the war at any time at all, their shipping would have been sunk and they would have been under siege from the moment they did so.
The larger cities were receiving a good number of aerial bombardments and V2's (ok, also a form of aerial bombardment). And then there was the shipping tonnage sunk with all hands.
War very much came to the UK, even if the eventual battle took place in France, Belgium, NL and eventually Germany (where whole cities had been obliterated).
Not so for the USSR, since it had been designated as "Lebensraum".
This kind of verbal white-washing causes all kinds of problems when the inevitable adjustment happens which shows that we can play word games all we want but it won't make an actual difference.
A draft would change this. But the military is a product like anything else. It's not civil service. It's not something that every family suffers from. The U.S. professional military is overwhelmingly middle and lower class. There's no meaningful representation of aristocratic families in the military. They have nothing to lose by supporting politicians who in turn support interventionist policies abroad.
When discussing foreign policy on an internatioal medium it would be helpful to formulate your responses by specifying the hypothetical combatants and coalitions explicitly rather than implicitly (i.e 'we' is an ambiguous definition in this context).
