I pessimistically expected that.
If he bowed out and the Dems nominated a halfway decent candidate (which they likely wouldn't do, but that's a different subject), they'd demolish Trump. He'd lose so badly he couldn't even pretend it was fraudulent (though of course he'd claim that anyway, since he has the emotional maturity of a spoiled five-year-old). The race would instantly go from a terrifying risk to a complete rout.
But between Biden's ego and the DNC's determination to stick with a wholly-owned establishment neoliberal hack at all costs - even if it means losing - I expected that they wouldn't take this golden opportunity.
None.
I think that the exact measure of whether or not a war is justified is whether or not people are willing to fight it.
It's very rare for a war to be a direct threat to the people. That's generally only the case in a situation like Gaza, in which the invaders explicitly intend to not only take control of the land, but to kill or drive off the current inhabitants.
As a general rule, the goal is simply to assume control over the government, as is the case in Ukraine.
So the war is generally not fought to protect and/or serve the interests of the people directly, but to protect and/or serve the interests of the ruling class. And rather obviously, the ruling class has a vested interest in the people fighting to protect them and/or serve their interests. But the thing is that the people do not necessarily share that interest.
And that, IMO, is exactly why conscription is always wrong. If the people do not feel a need to protect and/or serve the interests of the rulers, then that's just the way it is. That choice rightly belongs to the people - not to the rulers.
