What I gather is that nations are like car buyers, they first fall in love with a war, then shop for one to buy and only later work out how to pay for it. It is not so much that Belgium is in fact important to Britain, but rather the symbolism it provides to quiet the objections and craft the consensus to buy into a new war. Taking away the "Rape of Belgium" leaves open the possibility the consensus itself cannot be had and even if a majority can still get a war the lingering lack of consensus opens up doubt, recrimination and worst of all, political opportunism. As the war gets costly the opposition can steal your voters. And I think the Liberals feared more how the Conservatives would profit from a peace than they could profit from a war. But that does not get a consensus here, Britain has great reasons to pay for the war but it might not buy. And that is good enough for me, it leaves an ATL where the groundwork is set to have a non-belligerent Britain. And I think the consensus is that Britain will be a rather insincere neutral, playing an obvious double game, and losing any pretense to being a fair player.
There appear to be yet more opportunities for Britain to buy into this war but as the war rages on less enthusiasm as we see before you know what a bad buy it is. And we still have Germany able to blunder its way into dragging Britain in, a thing they excel at. If Germany can navigate the waters the British Empire is left in power, intact and the last Great Power standing. Germany has gained a lot on paper but must make good. The USA is in the wings to notch up and Japan as gained a new level. But I still have yet to see how bad the world is with the siren call of German dominance over Europe. And perhaps that is the next debate.
And if we can see past the reluctance and get the UK at war, wholly made of cloth now, we find no consensus for how she uses the BEF. Worse we have scant consideration of how deep in does Britain invest once the Western front stagnates. A valid tangent, each tangent reveals something, but here the British are not fighting a noble war of salvation but a cold war of geo-politics, it is toss men into the grinder daily to play a game, a game that the voters will weigh in on when the war ends, and I think it must end well or the British will find more revolution in their air than they care for. And that too is another debate.
The British are either painted cowards or opportunists, they are perfidious either way really. Without Belgium I find a naked truth.
