Is it just fighting in Eastern Europe you are not happy about? If Russia invaded France or Germany, do you think that people should fight then?
What about if they dropped bombs on us? Should we fight then? Or just rage at the government via the internet?
Curious as to what your tipping point would be?
The world works on alliances - always has done. It's why WW1 started after Franz Ferdinand was assassinated and its why NATO is so important - the idea of NATO is that all of the countries sign up to the attack in one is an attack on all principle - as soon as we start to discriminate between NATO countries, the whole thing goes south.
We can't say I wouldn't fight to defend an Eastern European NATO country, only a Western European NATO country, or even worse, I'd only fight to defend ourselves because that leads to the collapse of the alliance and then everything truly will descend into chaos.
That is why the risk of the US leaving NATO is so dire - not because we would miss their military might in any conflict (although that is also an issue - albeit one which Europe is trying to mitigate), but because it fractures the united response which has prevented another world war breaking out up until now!
Would I want my children to have to go and fight in a war - of course not. Do I agree with war in the context of the current crisis - no, as a previous poster said, it is all about rich, white men seeking money and power.
However, if it comes to it and we do end up in the sort of war that needs conscription, then yes, I would absolutely support it and encourage my children to do their bit in any way that was needed, as would I, because the alternative - of powerful countries being able to take over, invade and ride roughshod over whoever the hell they want, is completely horrific.
As it is, I don't think it will come to conscription for our young as there was in WW2 with young people being sent to the front to fight. I think there will be challenges and sacrifices that need to be made, I think there will be difficulties and there may be conscription within home based industries / engineering / factory production / food production.
When NATO countries get fully drawn into this, it will be an information and technology war - there will be some soldiers on the ground, but a lot of the battles will be with aircraft and drones. There will be attacks on the internet and on information systems to try and cripple the country. It will look very, very different to the 1930's!
