I doubt that. It's far more likely to backfire into increased support for aggressive right-wing populism of the kind Trump peddles. It also seems doubtful that Europe could really afford that economically at the time when it's already in an open confrontation with Russia and not exactly on friendly terms with China.
> does anyone see any other way to reign in the warmongers? What say you, Americans? You are, after all, the only effective mechanism by which your own war mongers can be brought to justice.
We do not have an effective mechanism for that. Even if our democracy were truly functional, people have voted for candidates who promised no more wars for >15 years now, and yet here we are. Meaningful reforms that would _perhaps_ enable this require constitutional amendments, which have such a high bar as to be unattainable in this political climate. I don't think the system can recover, but it still has a lot of capacity to do damage as it breaks down.
